>>For genuine cases, such as setting the radio strength on a wifi card, manufacturers might put that bit of the driver in ROM. If there is no cost to them, then manufacturers will DRM the entire driver (instead of just the radio strength bit), and will tell the free software community "Sorry, we're complying with regulations".
No one in the aviation business is foolish enough to put their avionics software into a ROM. FAA and other regulators require the ability to update the firmware to fix critical issues. You would never be able to ship a product as you would fail certification.
You may not realize this but ROM costs far more than FLASH based memory for large sizes. I can't think of a single device that I make or have worked on in the past three years that uses ROM for any storage.

about "put it in ROM" Posted Oct 18, 2006 13:20 UTC (Wed) by coriordan (guest, #7544) [Link] They can also put the software-containing-whatever in a locked box. That's another thing GPLv3 can't prevent and doesn't try to prevent. Or they can send out a worker to take out the dodgy ROM and put in a working one. But these are corner cases. If GPLv3 is perfect for every application except for the critical parts of some avionics software, that's not a big problem. Being suitable for 99.999% of applications would be just grand. The avionics industry might just have to write some of their software themselves (but I suspect they do this already). (I put my previous commented into my blog: Preventing modification: put it in ROM?)

That's some tortured logic. How are you going to cut out option 2? The GPLv2 will still allow it and clearly there are a large number of people who are still interested in its existence. Besides, option 2 is a freedom that I personally value highly. All this talk of restricting what you can and cannot do with the compiled software... If the FSF shares your view on freedom, maybe it's time for them to change their name to the "Free Sourcecode Foundation"?
about "put it in ROM" Posted Oct 19, 2006 11:28 UTC (Thu) by coriordan (guest, #7544) [Link] GPLv3 cuts out option #2. GPLv2 will still have option #2, as will many other free software licences. Developers can choose what licence to use.
The way that GPLv3 cuts out option #2 does not interfere with "what you can and cannot do with the compiled software". GPLv3 only says that if you distribution a software+hardware system, and if you rigg the hardware to malfunction if the software does not have an approved fingerprint, then you have to also distribute whatever digital magic dust is needed to authorise a fingerprint.
So this only places a requirement on people who are distributing products which combine software+hardware, and which are specially rigged to prevent running software modification. It is very unlikely that this includes you. It doesn't include any of the Linux hackers, AFAICT, and it doesn't include Red Hat, or Debian, or SuSE, or Ubuntu. It is only an additional requirement on the company behind the Tivo, and some router manufacturers.
