No, you're the only one who got the point and someone needs to mod you up. This is quite wrong:
|Apple has not put themselves into a position of power over the FLOSS community with this move, as a GPL3 fork could be started at the drop of a hat, from whatever the last compatible release was.
Apple is in a position of power because they now own the CUPS copyright. They are only distributing it under GPL2/LGPL2, and it is not, and has never been available under that license "or any later version," so we can't make a GPL3 fork. The only entity that can get it into GPL3 (or any other license) is the copyright holder.
In the short term this is fine, as GPL2 is a good license. But Apple reserves the right to stop licensing it under the GPL. You could fork the project, but your forks would always have to be GPL2 forks (again, this is not exactly a disaster). But Apple can also make their own internal company modifications specifically for OS X, yet not release the changes to the community. They are no longer obliged to release the OS X version's changes because it will presumably be covered by the Apple EULA instead of the GPL. The only legal escape is to wait until the copyright expires in 70 years or so, then take the expired version's public domain code as your own and license it under the GPL3 or whatever. Get back to me in 70 years if you decide to try that. I'll beam over and help you update it.
