"Industry" has failed me (and the users in my little niche) many times over. WTF would I give a damn what they want?

If I released my code under permissive terms, I'd be effectively paying them to screw me over again. That'll sure show them!

There is no compromise with someone who doesn't believe you have the right to exist. Keep that in mind when you talk about compromising ideals.

That lines highlights the issue with the GPLv3 and the reason why it shouldn't be used much better than anything else.

The truth is different: extinction is much worse than even the “compromise with someone who doesn't believe you have the right to exist”.

But in the end, as I have said, it's your choice: if “free software” camp want to become just an article in Wikipedia about yet another group which no longer exist… who am I to judge them?

Care to write an article which explains how “industry” have failed you, and, more importantly, how you are thriving now without them?

I'm sure people on LWN would appreciate it. As cautionary tale if not anything else.

The entire purpose of the "tech industry" these days is to sell advertising (and/or access to "content") on locked-down appliances. "user empowerment" as embodied in the "Four Freedoms" is in direct conflict to this.

But your takeaway is that the GPLv3 is the problem, rather than the ones seeking to repress users? WTF?

Printers. I've said here in the past that I've been threatened with lawsuits by companies that were actively distributing (if not outright using) my code -- Code that I only wrote because they refused to support Linux users.

Meanwhile, the actual "need" that got me into this area to begin with was a brand-new printer with memory card slots that couldn't handle abitrary jpegs... and also violated the flow control portions of the USB printer class specification.

And yes, by any objective standard, I'm thriving. My personal printing needs are well met these days, and I've been able to leverage this work into a (very) modest consulting business that pays for more creative-outlet-type devices (most recent one was a laser engraver that runs GPLv3-licensed GRBL).

… because that's the only thing that you can actually make and sell. It's not as if there are no attempts to create other types of devices — people are just not buying these.

GPLv3 is a problem because it's expressly designed to make sure code released under that license wouldn't reach actual users and would forever stay irrelevant.

Yes, it was brave attempt to change the industry rules… and it failed. Time to move on.

Interesting. This means that while industry-at-large changed and now using GPLv3 for something like uutils just means that nobody would bother to even look on your creation… yet at the same time certain niche markets appeared where GPLv3 is not considered large enough liability to try such software.

This certainly is an interesting example and article may show how more such niches can be found (or made?). That would mean that “free software” may still be relevant to some people beyond core “die-hard believers”. And certain types of software may actually exist as genuine “free software” because of that.

I wasn't aware such niches remained. All the software I develop and use is either:

Used by billions of people — and then, of course, GPLv3 is just flat out unacceptable, or
is niche enough that you can't make a business out of it — and then GPLv3 is irrelevant since there are noone who would misappropriate it in the first place (since there are no money in it)

If you may show where “free software” can be actually useful then it would be 100 times more important than whining about the desire of uutils makers to create something that people would actually use.

Of course there are other types of devices, and real people do buy them. There is a considerable middle ground between "tens of millions of units shipped in a quarter" and "nothing".

"free software" isn't inherently useful, except in an abstract educational sense. But "useful software" is made more so by being "free".

Yes and the resources to pay engineers and develop software are a direct function of that volume.

Those aren't mutually exclusive, and in any case, my quote says nothing to support the assertion that GPLv3 was "Expressly designed to make sure code wouldn't reach actual users and would stay irrelevant" (I'd think such an absolute declaration as to the intents of the GPLv3 would be trivial to cite, as the whole drafting process was quite public)

And do I really have to point out that the software world is *much much much* bigger than the "tech industry"?

The whole thing was designed to fight tivoization. It wasn't the only reason to create GPLv3, but that was the main one. And the expected outcome was that hardware manufacturers would just make it possible to change the code on a device they sell.

But it was really quite naive to expect such an outcome in a world where the same hardware is sold to a different users at “differentiated prices”. Think Intel's CPUs or compare prices of TI-NSpire and TI-NSpire CAS (not only they have identical hardware, their sales rely on the inability of the buyer to tinker with their software… they are not doing all that good of a job ensuring that, actually, since they only need to claim that it's impossible to change the software, they don't need to make it actually impossible — but that stil absolutely precludes use of GPLv3 software).

FSF hoped to, basically, change the business models of many different industries, laws (that's very explicitly written there, look on section #3), the style in which governments operate — with very limited reward: the ability to use some software for free. No wonder the attempt backfired.

It was a gamble: we may change the rules under which the whole world operates or we would be kicked out of mainstream and relegated to tiny, insignificant niches. But GCC looked so entrenched, Linux was so popular… the die was cast. “Free software” lost.

> And do I really have to point out that the software world is *much much much* bigger than the "tech industry"?

Indeed. And since software replaces hardware more and more it becomes more and more important for the developers of hardware to stop unauthorized modifications. For market compliance and other reasons.

Indeed, that was pointed out to FSF many, many times during the GPLv3 drafting. And it was altered to accommodate some such uses (look for distinctions WRT to “User Product”, e.g. — it's there specifically to allow producers of industrial devices not intended to be used by “Joe Average” to be able to delived locked-down hardware to their customers who very expressly don't want the ability to change the code on a device with associated liability). But it was very obvious even back then that such cases would become more widespread, not less (heck, look on #3 “Protecting Users' Legal Rights From Anti-Circumvention Law” again).

In a world where problems in software may lead to, at most, some papers being incorrectly printed GPLv3 may have been acceptable (yet, ironically enough, it was also not needed in such a world). In a world where software drives literally everything… it's unusable and ensures that end-users would never see your software.

Relying on software to fix hardware bugs is the norm novadays and it's much, much, MUCH simpler to rely on the locked down, signed, firmware instead on some nebulous schemes which may detect and alter modification of core system library (like libstdc++) and save the hardware anyway.

It's certainly nice that some niche industries may still afford to use GPLv3 and I really would be glad to read your article about that (no sarcasm here) but GPLv3 was expressly designed to make sure software under said license wouldn't be acceptable for many, many, MANY industries and thus would never reach the end users.

This may have been the end result, but it is was not the "Expressly designed intent", as you yourself said in the very first sentence of your reply:

> The whole thing was designed to fight tivoization. It wasn't the only reason to create GPLv3, but that was the main one. And the expected outcome was that hardware manufacturers would just make it possible to change the code on a device they sell.

(though that should be "continue to make it possible" -- manufacturers have to do considerably more work to create a locked-down device than not)

Anyway. In my experience (based on discussions with the last two $dayjobs' legal staff) it's not the anti-DRM clauses that made the GPLv3 a pariah -- that was a minor nuisance, easily worked around via technical means. The patent language, however, was the RealProblem(tm).

Locked-down devices predate not just GPLv3, not just the whole GNU project. They go back to early days of the IT industry. IBM sold features which would be unlocked (by installation of some SMS cards) back in 1950th, TROS modules in 1960th and so on.

Yes, it was relatively easy to circumvent these limitations (compared to RSA signature in modern devices) but that's not something people invented just to make FSF angry at them.

GPLv3 needs entirely new scheme, though: the one where you can change part of your base system software but not the whole thing.

That is certainly harder to achieve than full lock down of the whole thing.

How is that substantially different from Apache license? It also includes the patent grant. And is loved by the industry.

For the "tech industry" as a whole, the "user" is not the "customer" -- as in, those _using_ the product/device/whatever are not the same parties who actually fork over money. In those scenarios (and other business models where hardware is sold at a loss and made up for on the back end), locked-down devices are economically advantageous.

For everything else, barring legal/regulatory anti-tamper requirements (which are actually quite rare), there simply isn't an economic incentive/advantage to lock the hardware down; indeed it doing so can actually place you at a competitive disadvantage (because it both raises your costs and _reduces_ end-user functionality/utility)

In my two decades of experience in this field, the general concept of copyleft as a whole is the problem -- businesses simply don't want to have to comply with source distribution requirements and the risk that their "secret sauce" is forced into the open due to viral GPL contamination. Nevermind that having the processes to maintain/track the "software supply chain" is a practical necessity (ie _not_ having it can be a massive liability even without copyleft/GPL)

Once they accept the practical realities of having some GPL software (ie providing corresponding source code and keeping their proprietary stuff, if any, properly segregated), GPLv2 vs GPLv3 vs MPL vs SCCL or whatever is largely irrelevant... unless you have patents you're trying to protect/enforce, and the GPLv3's explicit patent license can possibly render your business' entire patent portfolio effectively useless for anything other than purely defensive means. That scares the bejeebus out of the suits, so the edict comes down that GPLv3 is bad, along with the funding to avoid its use, even to the point of wholesale development of in-house replacements.

You still haven't explained what makes explicit patent grant in GPLv3 worse than no less explicit patent grant of APL. And APL is certainly warmly embraced by the industry.

While both licenses have explicit patent grants, they differ greatly in scope.

ASLv2's patent clauses kick in only for _contributions_ to the software (ie "by contributing, you're granting a license for all patents you have that relate to the software") , but GPLv3's patent clauses go considerably further, applying even if you merely redistribute unmodified 3rd party software covered by a patent you hold or have licensed.

It's just one example but I worked on a project that forked the last GPLv2 version of GRUB for pure tivoization reasons. No one at $BIGCORP ever seemed to care about any GPLvX patent difference, it's all about the tivoization difference, in fact there are mandatory trainings about the latter and not about the former.

macOS has been stuck to the last GPLv2 version of bash for years, now switching to zsh. Same for other software on macOS.

Same timing all across the industry, what a coincidence!

Pardon? What about the GPLv3 doesn't give people the right to exist?
