khim, I am really struggling with making sense of all your statements. Even with a lot of goodwill and creative interpretation, I have a hard time making sense of your post.

> Google does not mind GPLv3 for the developer tools

OK, but the gambit failed, so I guess it is everybody else that saw GPLv3 as a little too much for GCC then. Exactly who are we talking about? Apple? From all I have found it was the copyright transfer of LLVM to FSF that stopped them from collaboration, before GPLv3 was a reality. AFAIK, Apple going for LLVM outside GCC had nothing to do with version 3. Do you have *any* information to back up your undocumented stream of statements?

> that's why Android comes with no libstdc++.so.*

Care to enlighten me, exactly what legal issues are there related to using libstdc++? AFAIK it is linked in just about any proprietary application out there.

> there are talks about switching to LLVM and libc++

Yes, but that may have many reasons, and may or may not materialize, and if it does, it will be because somebody regards it as technically superior. The license of LLVM is about as primitive as BSD, and lacks any reference to patents. With Google opting for Apache, I am pretty sure any switch to LLVM will be despite its license, not because of it.

> they need phones lockable by carriers to be successull in the smarphone market (they only company which gets away without such lock-in is Apple and this partially because it offers it's own lock-in which means that tethering is still not allowed if carriers don't want it to be allowed).

Please provide documentation that HTC lost carriers over offering tools to root their phones. I don't believe you will find any, and that basically nullifies you theory right there. Next time read my post before answering, I have provided explicit examples documenting my statements, I really appreciate if you counter them in a more scientific manner.

> Oh yeah. Lock-down is vital for iPhone success. No, not directly, but indirectly: without carrier subsidies iPhones are too expensive in many parts of the world and carriers will not support them if they can not gurantee they'll not work as carriers want.

It seems most of the world has the opposite conclusion, that Apple with Iphone demonstrated that they could strip carriers of their demands and make a great commercial success of it. I would actually say that not allowing carriers to control software on Iphones is the main reason why Iphone was a success. I want you to document your claim here, and tethering just doesn't cut it. It is a really minor point in this setting, nothing that anybody seriously believes would cut Iphones out of the market.

> From Android example we see that all such tries will lead to rejection of software (most GPLed software is already removed from Android

Google choosing linux as kernel has been a tremendous success for both Google and linux. Choosing any other kernel would be plain stupid, we have enough driver issues on Android as it is. I think Google would have done the smart thing and gone with linux whether GPL2 or 3. Would be good if somebody from Google could comment on that though, since we seem to be in a dead-lock on this one.

> most GPLed software is already removed from Android except for kernel and GCC is well on it's way to deprecation partially because of the same issue

This is getting very annoying. Have you changed the whole subject from GPLv3 being a mistake, to claiming that copy-left/GPLv2 is a mistake, and that GCC should be permissively licensed? This is starting to look like drivel.

You seem to believe GPLv3 failed, while arguing that GPLv2 also is a failure when it comes to Android, making the whole v2, v3 discussion moot. Make up your mind, do you believe that copy-left makes sense? If not, then your whole gambit comment is just stupid deception. For your information Black duck posts statistics on license usage, here:
http://www.blackducksoftware.com/resources/data/top-20-op...
Unfortunately, they do not distinguish between GPLv2 and GPLv2+, but as you see, the GPLv3+ projects are just as popular as Apache 2.0 (which is by far the most popular permissive license). Counting in GPLv2+ projects (which is also available under GPLv3), I believe you are looking at GPLv3 being the most used open license in the world. Chew on that one for a while.

Basically, FSF said to industry: "F**k you, moochers. Let's see how you'll do without our precious GPL software"

Turns out that industry can do just fine without GPLv3 software. So now we have lots of non-GPL tools that are comparable or better than FSF's ones. Exceptions exists, like Samba, but even that gets worked around.

No they did not, there were several drafts and the industry was consulted. In particular, the anti-Tivo clause was changed to only protect ordinary consumers. As already mentioned, the patent clause is already adopted by the whole industry. The only indication I have seen of GPLv3 being one too many, was Linus refusal and consequently linux and git using a GPL2 only approach. I am sure there are other following that example, but I have yet to see any. Maybe you can provide some examples of GPL2 only projects?

Did you just wake up or something? The industry has *always* done fine without GPL software regardless of version. BSD and Apache have been around for quite some time you know. However, it seems GPL has opened the minds of corporations towards open development. They basically want the developers, but not the commitments, hence permissive licensing. Hence, many companies are now investing in open software. Software houses tend to like permissively licensed code or dual licensing, since they want both ends of the deal. Customers and communities are typically best served by copy-left. Both have their place, and there is no drama in it. In fact, you and khim more and more appear to me as astroturfers. Exactly what is your take in this? Are you here just to sabotage copy-left, or do you actually believe that the world is best served by abandoning copy-left altogether?

Sure, and the industry said that it's unacceptable.

Not really. GCC, gdb, glibc, busybox and others used to be indispensable. So indispensable that RMS used to call Linux as GNU/Linux.

Well, not anymore. Gcc is being replaced by clang+LLVM, gdb is being replaced by lldb and so on. All of the replacements are under permissive licenses (Apache or BSD).

>However, it seems GPL has opened the minds of corporations towards open development.
Be that as it may, it's not the point of the argument. Large organizations figured out that collaborating on non-essential software is better than reinventing the wheel all the time. They are also absolutely allergic to GPLv3 which denies them ability to keep ESSENTIAL software controlled.

>The only indication I have seen of GPLv3 being one too many, was Linus refusal and consequently linux and git using a GPL2 only approach. I am sure there are other following that example, but I have yet to see any. Maybe you can provide some examples of GPL2 only projects?
Sure. Apple ripped out Samba from Mac OS X - it's replaced by their own SMB implementation. They've also replaced gcc with clang - the last available officially supported gcc on Mac OS X is the last non-GPLv3 version. And Google avoided GPLv3 completely.

BTW, can you name a single GPLv3 project that is used consistently across all the architectures? I can't.

>Exactly what is your take in this? Are you here just to sabotage copy-left, or do you actually believe that the world is best served by abandoning copy-left altogether?
Basically, I think that copy-left is a nice idea in small quantities.

They surely did not, GPLv3 code is used everywhere in all industries. Major contributions are being made by industry to various GPLv3 projects too. BTW, why are you pounding that dead horse, you do not believe copy-left is a good idea in the first place (otherwise you would probably be evangelising usage of GPL2-only or LGPL licensing by now).

> Not really. GCC, gdb, glibc, busybox and others used to be indispensable. So indispensable that RMS used to call Linux as GNU/Linux.

They were always dispensable, there used to be many operating systems around remember? are you so quick to forget the BSDs and the Unix variants? Or windows, or OSK or OSX or IOS or .. This is getting boring. You are a smart guy, stop saying things you know are stupid. Actually, the last years copy-left has conquered HPC world wide, it is about to conquer the web-servers, and the BSDs need to turn to copy-left for the three most popular desktops. How about end-user applications, show me your permissively licensed apps? Don't be naive, without copy-left many of us would not be able to work with open source at all. We all need it. Its usage is growing, and it is fuelling the current growth of permissively licensed projects. Make no mistake though the majority of projects are still copy-left, and they are growing stronger despite Microsoft and Apple doing their best to sabotage it. Stop helping them please.

> Be that as it may, it's not the point of the argument. Large organizations figured out that collaborating on non-essential software is better than reinventing the wheel all the time. They are also absolutely allergic to GPLv3 which denies them ability to keep ESSENTIAL software controlled.

Large organizations are not allergic to GPL regardless of version. To the contrary they gladly pay Red Hat for it. Moreover, many of them are smart enough to see the benefits of copy-left. For some software houses it is different, but I hope and believe that the two most prominent ones (Microsoft and Apple) will pay a hefty price for their hostility towards copy-left and consumer rights in general.

> BTW, can you name a single GPLv3 project that is used consistently across all the architectures?

You mean operating systems not architectures, right? Of course, GCC and Gimp are used across all desktop OS families successfully by many. But you probably want me to name GPLv3 projects distributed by Microsoft and Apple for their operating systems, right? Why limit yourself to that, neither of the are fond of copy-left at all, so simply say GPL instead. Unless you have an invested interest in creating confusion.

> Basically, I think that copy-left is a nice idea in small quantities.

Thanks for showing colours. That basically leaves you with Microsoft and Apple as your goto place for software. Copy-left is very hard to get by without on any other platform if you want any kind of user experience. I suggest you run along to Apple and ask them for a permissively licensed desktop and apps. See how far your ideology takes you. Yes, ideology. I am afraid I am the pragmatic one among the two of us. Right now, it seems Apple's hostility towards copy-left is costing all ios users access to a wave of new apps:

Personally I am finding myself using more and more open apps on android, and yes, with a GPL license.

Wrong. Stop deluding yourself.

iDevices and Androids have no GPLv3 software. Whatsoever. And they outnumber personal computers by now.

So?

LGPL with static link exception is fine. GPL for end-user software is also OK-ish.

> They were always dispensable, there used to be many operating systems around remember?
Nope. Even FreeBSD was built using gcc, there literally was no free alternative. Remember?

> Large organizations are not allergic to GPL regardless of version. To the contrary they gladly pay Red Hat for it.
Can you understand what people write to you? It's perfectly OK for large companies to use GPL or even GPLv3 for infrastructure or non-essential services. It can't harm anyone that way. They might even throw a patch or two to tweak something.

But no large company produces devices with GPLv3. And just how many end-user devices with RHEL are being produced?

>You mean operating systems not architectures, right? Of course, GCC and Gimp are used across all desktop OS families successfully by many.
There's no GIMP on iOS. Or Android, for that matter.

> iDevices and Androids have no GPLv3 software. Whatsoever. And they outnumber personal computers by now.

It is one industry, one datapoint. There is more in this world than smartphones. Stop making wide ranging statements when you really mean very specific usage. Android certainly do have GPLv3 licensed software in numbers, but you may refer to the operating system? Well Android is pretty stripped down, with only a custom Java engine to run the apps. The choice of using apache was maded specifically because HTC and the rest wanted to use an open core model from my recollection. It is an interesting dynamics, and shows a natural usage of permissive licensing. This may have nothing to do with version 3.

Let me help you out a bit. First up there is the boot-loader. Recall how lilo was very popular, but now all distros use Grub? Guess what licenses those two have? Does Google use Lilo for Android? Nope, of course not, they don't use Grub either, and mostly because Grub has a ton of functionality Android does not need. Same with SurfaceFlinger, do you think they did it because of the xorg license? Wow, Google really must hate the X11 license, wonder why Apple likes it... Now over to your favourite glibc, well do you remember the ordeal with Ulrich Drepper refusing patches for using glibc in an embedded setting? Debian forking glibc over to eglibc. Do you think maybe that could have somewhat more to do with bionic than the license? You are a smart guy, I am sure you get the drift. Again, somebody from Google speaking up would be nice. Not saying I know the priorities, but your conclusions are not very convincing to me.

> LGPL with static link exception is fine. GPL for end-user software is also OK-ish.

Hm, I cannot make any sense of what you are trying to say here.

> Nope. Even FreeBSD was built using gcc, there literally was no free alternative. Remember?

Let me help your memory. BSD used to have *drums*, a BSD licensed compiler: http://en.wikipedia.org/wiki/Portable_C_Compiler
You really need to get your history straight, copy-left ran the pants of anything BSD had to offer. It is your very good friend Apple and its fat wallet you can thank for BSD having another go at compilers. Seems they have a lot of money to spend on astroturfing these days too, I have never seen so many lies about GCC spreading before. Those unfamiliar with history is bound to repeat the mistakes, and it saddens me that so few care about the history.

>But no large company produces devices with GPLv3. And just how many end-user devices with RHEL are being produced?

and you know why, don't you? Does the name Elop ring any bell with you, at all? Did you have the pleasure of using the N9? A part from that GPLv3 has made success in network routers, Linksys (yes that was Cisco, do they count as large you think?) even marketed it. Any NAS box these days come with Samba, does Hewlett Packard count as large in your book by any chance? This is just getting stupid, I think I will stop here.

Actually, there is not. Smartphones this year outnumbered all other computers, except for microcontrollers.

:facepalm:

And gcc is only a translator from C++ to machine code. And Linux is merely a wrapper over hardware-provided services. And Google is simply an indexer.

>The choice of using apache was maded specifically because HTC and the rest wanted to use an open core model from my recollection.
Nope. Android was designed this way to allow carriers to lock down phones, and total avoidance of GPL was a pre-emptive step to avoid being forced to support GPLv2 forks indefinitely.

>Well Android is pretty stripped down, with only a custom Java engine to run the apps. The choice of using apache was maded specifically because HTC and the rest wanted to use an open core model from my recollection.
Google uses Coreboot which is GPLv2 on Chromebooks. JFYI. Lots of Android devices use U-Boot which is, you guessed it, GPLv2.

> Let me help your memory. BSD used to have *drums*, a BSD licensed compiler: http://en.wikipedia.org/wiki/Portable_C_Compiler

No they didn't. The first attempts to use PCC to compile FreeBSD were made in 2007 or so. It has never been used in anger, unlike Clang.

> and you know why, don't you? Does the name Elop ring any bell with you, at all? Did you have the pleasure of using the N9?
So there's no phone with GPLv3 software out there. Even the new Jolla phone does NOT have GPLv3 anywhere, though they have quite a lot of GPL and LGPL software on it.

Again, it's either isolated or used in non-core parts. Or in situation where GPLv3 has no bite at all.

So yes, it only reinforces my point: GPLv3 failed miserably.

GCC is a compiler collection, it can do much more than Java.

Sloppy again are we. There is plenty of GPL code in Android as I am sure you know. You mean version 3 I guess. You may or may not be right. Like already mentioned, Android avoids GPL in user space due to it's open core model.

> So there's no phone with GPLv3 software out there. Even the new Jolla phone does NOT have GPLv3 anywhere, though they have quite a lot of GPL and LGPL software on it.

Actually I do believe you will find GPLv3 software on N9, basically from the Debian stuff. But you are right when it comes to Jolla not shipping GPLv3 in shipping images, here I found the documentation for you:
https://wiki.merproject.org/wiki/Architecture#GNU_utilities
Nokia on the other hand was big enough to make a difference, and Microsoft made sure that never happened. I would say Microsoft did a bargain when they got Nokia on board with an exclusive deal, worth every billion. However, GPLv3 software is easily available in abundance on Sailfish, Meego and Android. On a related note, Jolla does ship glibc, did you know that?

> Again, it's either isolated or used in non-core parts. Or in situation where GPLv3 has no bite at all.

You were flat out wrong, and are back-paddling desperately. May I suggest that you just admit it, GPLv3 is not that big of a deal on devices. Sure, there are manufacturers that want to lock-down devices, and they will probably avoid Grub. That's no biggie, Uboot serves them fine.

Just listened to Langley's talk, and it makes me depressed.

There is _no_ GPL (of any version) in Android images and even no LGPL anymore. Android tools certainly use it.

>However, GPLv3 software is easily available in abundance on Sailfish, Meego and Android.
Sure. They don't limit third-party software, so they can't care less.

Which is LGPLv2.1

> You were flat out wrong, and are back-paddling desperately.
Nope.

It IS a big deal on devices. So big that big vendors essentially forked the entire FSF stack to avoid it.

LGPL is most certainly there: KHTML^H^H^H^HWebkit^H^H^H^HBlink^H^H^H^Hwhat-the-name-if-this-thing-today still includes few LGPL-licensed files. But all the new development there uses BSD (not Apache, BTW, but BSD) thus it's pretty limited and constrained.

Ah yes, apart from Linux itself, of course. But Linux is an exception somewhat - it has a non-existent GPL enforcement and it's also firmly in GPLv2 only camp.

However, there _are_ Android implementations that do not even use Linux - Blackberry runs their own Android simulator atop QNX.

Not true. netfilter is enforced by its copyright holder, and several other kernel copyright holders have thrown their lot in with the SFLC. I'd guess that the only piece of GPLed software with *more* license enforcement than the Linux kernel is busybox.

Down to semantics are we. U-boot not being part of the image you mean? What are you trying to prove, that what Google forked and made themselves in user space on Android was permissively licensed? We agreed on that already. Just forgot, Uboot is GPLv2+ so available under GPLv2, but also available under GPLv3. A tiny fact you jumped over earlier in this thread.

So let me get this straight. You're saying that in a NAS box, Samba - the GPLv3+ SMB1/2/3 implementation that ALLOWS THE BOX TO FUNCTION AND IS THE ENTIRE PURPOSE OF THE PRODUCT is a 'non-core part'.

Hmmmm. I think you might want to look at the lifeboats. The argument is desperately listing and taking on water at an alarming rate :-).

That's exactly what I'm saying.

Your core part is something that you differentiate on from your competitors. For SAN the most interesting part is their core storage management which is far out of reach of GPLv3.

For end-user NAS boxes companies usually have no differentiating features at all (except the components price that you can get from your Chinese suppliers). So the vendors don't mind putting GPLv3 on them.

Looks like you're conflating "core" and "differentiate" there. SMB is a core feature for any kind of NAS storage box. Now, with Samba out there, it may be hard for vendors to differentiate themselves on it, so they have to find some other feature that differentiates them (which may also be a core, required feature for a NAS to have, but also need not be).

Nope. That's your code *competency*, which is a business/management term http://en.wikipedia.org/wiki/Core_competency.

The usual engineering interpretation of the term is very different, and more in line with the FEMA definition: https://www.fema.gov/core-capabilities. Basically a core "part" is something you *require* to achieve a goal, not something that distinguishes you from the rest.

At least that's how I see it.

It's *very* expensive to work around Samba :-).

Another one just bit the dust - NetApp just bought HvNAS (hvnas.com now redirects to NetApp), probably to try and shore up their increasingly creaky SMB2 implementation (leaving HvNAS's existing licensees holding a flaming bag of %*$# of course, but them's the breaks when you rent your code :-). Same thing happened to Likewise, but more proprietary companies got burned there.

> that's why Android comes with no libstdc++.so.*

Care to enlighten me, exactly what legal issues are there related to using libstdc++? AFAIK it is linked in just about any proprietary application out there.

But it's not distributed with these applications, right? Big difference. You see, libstdc++ uses straight GPLv3 (not LGPL!) which means that if libstdc++.so.* is shipped on device one will need to privide some means of installing it.

Now, why can “normal” proprietary programs can ever use libstdc++ if it's under GPL, not LGPL? Because they don't ship libstdc++ by itself and thus are covered by the appropriate exception. Said exception may or may not cover distribution of libstdc++.so.* as part of the Android image (it's not clear which part of exception will play if we are talking about libstdc++.so.* distributed in isolation), but Google is not taking any chances. In fact Google is busy bringing LLVM and Clang to the condition where they could replace GCC. GPLv3 is big part of the reasoning.

With Google opting for Apache, I am pretty sure any switch to LLVM will be despite its license, not because of it.

Not exactly. Google prefers Apache, sure, but if choice is between GPLv3 and BSD then choice is obvious (BIONIC was based on BSD libc, after all).

Please provide documentation that HTC lost carriers over offering tools to root their phones.

Why would it lose carriers if it's all too ready to lock phones again at their request? Yes, HTC made a mistake and issued unlocker which was usable for carrier-subsidized phones. Mistake is rectified so no biggie. I'm pretty sure someone at HTC got pretty good cheving over said mistake, but in the end status quo is restored. It was available in the wild for exactly one day—recall that usually updates take months till they are rolled out in the wild (that's true for HTC at least, some other manufacturers are faster) and this will say everything you need to know about the situation.

Make up your mind, do you believe that copy-left makes sense?

Once upon time it made sense. Not anymore. Landley gave tech talk which explains what happened and why. In nutshell: GPLv2 was kinda-sorta-accepted by industry and it was loved by open-source and free-software folks, too which basicallu put the situation at the uneasy truce. But GPLv3 became a land-grab attempt and this gave clear signal to the industry: you can not trust FSF (and ideally need to drop GPL altogether if possible). The backlash was stricking: not only GPLv3 failed to achieve it's objectives (I know exactly zero devices which were opened up because of GPLv3; the most I've seen are some proprietary programs designed to inject GPLv3 binary in otherwise tightly locked firmware) it made GPLv2 weaker.

Linux is kind of exception: it's developers were pretty vocal about their thought on said land-grab which means that industry don't need to fear Linux because it'll remain where it started WRT licensing. Other projects are not so lucky… well, Blink and WebKit are fine, too (they use BSD license for all new files and only use LGPLv2.1 for old files which may even eventually disappear). Some other projects could be trusted, too, but in general GPL went from “this is the beast we know” to “this is something we need to discuss on case-by-case basis”.

Counting in GPLv2+ projects (which is also available under GPLv3), I believe you are looking at GPLv3 being the most used open license in the world.

Right. <sarcasm>Let's add Apache and BSD liceses to the list, too (because, you know, they are GPLv3-compatible).</sarcasm> When this article was written almost 70% of projects were GPL. Straight GPL! Not GPL+LGPL+BSD+whatever-you-want-to-repaint-as-your-ally. Today… six years after release GPLv3 is still used by many times smaller number of projects than GPLv2 and even if you combine GPLv2 and GPLv3 you still have much smaller number that GPLv2 had ten years ago.

If the GPLv2 had the GPLv3 terms would it be the same situation we're in now, or was the act of adding the terms to all projects which used '+' the problem?

I don't think people would be avoiding GPL as much as they are, but I also don't think that it would be nearly as popular as GPLv2 was, and how much of the GPLv3 popularity is holdover from GPLv2 by people who don't know/care about the differences is hard to say.

I think the problem is a combination of both the terms and the change

on the one hand, if GPLv2 had the GPLv3 terms, I don't think it would have been as popular

but the fact that the terms changed in a way that many people consider very significant has also made it so that people don't trust the FSF to not make other changes in the future that could cause them even more problems, so they are much more paranoid about trusting GPLv3/GPLv3+ code than if the terms had been there from the start

It's true that a number of people probably didn't know what to think about the eventual result of the rather long and rather democratic GPLv3 drafting process, and as a result of that uncertainty, fuelled by punditry about the supposedly disastrous consequences on adoption by "the industry" by people who should know better, some people adopted the "footprint in wet concrete" approach to licensing and insisted on "GPLv2 only" for their stuff.

It's a shame, though, that these people didn't appreciate that some of the additional measures in GPLv3 - thinking of the strengthening of patent litigation protection - were becoming the norm even in permissive licences, whilst other things - thinking of access to the four freedoms in "consumer devices" - may already be governed by the GPLv2, although bkuhn can probably say more about these things (as I believe he mentioned the latter in particular at one point).

If anything can be said about attitudes towards the GPL, perhaps it can be concluded that the "look the other way" mentality about various edge cases in GPLv2 couldn't be sustained with GPLv3 applied to works, and those benefiting from that mentality were obviously upset as a result. But I hardly think that selective enforcement of licences and discretionary grey areas of licensing are a sustainable way of delivering Free Software to wider society: there's always the risk that someone will get away with something undesirable (making patents a "kill switch" for licensing conditions, for example) and then use some ill-advised discretion by a project to legitimise doing so, without exception and without limit, for all Free Software.

It wasn't a case of 'misunderstandings by people who should know better', it was a case of fundamental disagreement over what the requirements should be.

The anti-tivo clause is a perfect example. Linus stated that requiring that the code for the device be provided is good, requiring that you be given enough info to modify the software on the device was over the line.

that's not a misunderstanding of terms, that's a different requirement.

If you look at the angst that people have about secure boot and how some features need to be disabled or else the key will be revoked it seems very reasonable for companies who are building devices to be very worried about what the content providers would do to them if they gave out the info that let hackers modify the software on their devices to ignore any restrictions that are built in to the software.

you may not like that, but either it's a reasonable thing to do or this entire secure boot brouhaha is meaningless.

The FSF got a lot of feedback opposing this policy, but they decided that it was important enough to include even with all the opposition from opensource developers. And then they made it very clear that if this didn't end up with the result they wanted, they would make further changes going forward as they thought best.

this is the "I have changed the deal, and I will change it again if I want" attitude that many people saw that pushed them away from GPLv3

> In fact Google is busy bringing LLVM and Clang to the condition where they could replace GCC. GPLv3 is big part of the reasoning.

Please provide documentation. If you are only making this up as you go along, then please be honest about it. LLVM taking over GCC has been talked about for eight years now, and I see no sign of that happening yet. Actually, LLVM taking over GCC does not even make sense. LLVM is not a compiler, it is a project for creating compilers. If it out-competes parts of GCC, there is little preventing GCC from using LLVM as an optimizer tool. What I have seen over these years is GCC out-competing all proprietary compilers, with Intel as the last hold out. Yes GCC, not Clang, it doesn't even have openmp yet, so it will only be a real contender in a year or so.

> it's not clear which part of exception will play if we are talking about libstdc++.so.* distributed in isolation

So you don't know, and I am getting a bit tired of doing all the digging for you. Before you spout more statements, I suggest you dig further and figure out if bundling libstdc++.so with Android is a license violation or not. Maybe the Necessitas guys at Digia can help you out.

Why Google did bionic I don't know, but it can very well be for other reasons than license. Again, I have not seen any issues building proprietary stuff with glibc. After all, all applications on linux does it.

> Why would it lose carriers if it's all too ready to lock phones again at their request? Yes, HTC made a mistake and issued unlocker which was usable for carrier-subsidized phones.

Sorry, but I am starting to feel really grumpy. Let us sum up your findings:
-no carriers lost
-tool reverted for one phone in August 2013 (a weak and struggling HTC caving in)
-tool provided two years earlier (ref. http://www.htcdev.com/bootloader ), with no carriers lost for the entire two years
I call that pretty sound proof that the unlocking thing is a no-brainer. It did not shut anybody out of the market, and it will not shut anybody out of the market as long as somebody stands up. Right now you seem to be part of the problem, not part of the solution.

Actually this reminds me of when Netflix claimed that they could not make a version for linux because they needed the whole system locked down. Only silverlight could do the trick, and it was a demand from Hollywood. Finally, TI made a chip where they hard-wired DRM into it to satisfy the claimed demands of Hollywood so that the first Android device finally got Netflix. Fast forward a few months later, Netflix was available on all Android phones (apparently they could not withstand the anger of all the customers being left out). Only weeks later they started to provide patches for Netflix on CyanogenMod, at the time a totally DRM free version of Android.

I am sick and tired of intelligent people telling me that it is all hopeless, and that we should just give up. Giving up is not an option.

This is beneath you, you should know GPLv2+ provides the code "at the recipients option" under GPLv3. That is very different from blending in GPL compatible code. For all practical purposes you can regard GPLv2+ as providing the same rights as GPLv3+, only differnces is that you can mix it with GPL2-only code, and fork it to GPL2-only code.

> Today… six years after release GPLv3 is still used by many times smaller number of projects than GPLv2 and even if you combine GPLv2 and GPLv3 you still have much smaller number that GPLv2 had ten years ago.

And why do you think this is? I can only see two important factors in keeping GPL2 alive. One is that Linus fought it, and he is pretty influential. The other is that FSF made GPLv2 and GPLv3 incompatible, a terrible mistake that makes me want to cry.

You see, libstdc++ uses straight GPLv3 (not LGPL!)

This is factually incorrect. If libstdc++ used either license it would be nearly impossible to compile non-GPL C++ programs, because a lot of libstdc++ is implemented in header files.

See any file at all in libstdc++, and the Runtime Library Exception.

A license with this exception is GPL- and LGPL- and for that matter BSD-compatible, but it's not the GPL any more.

And, er, you said as much in the next paragraph. I wish there was a way to delete stupid comments on LWN (or maybe just my own).
