I think they're going to run into a problem there, though--technically, the only way the GPL has any force is if they're distributing something that is GPLed. It is the act of distributing copies that is illegal without a license, not the act of using something that has been made available. That is, if I buy a copyrighted book or CD, I don't need a license to read the book or listen to the CD; nor do I need a license to, for example, convert the CD's contents to MP3 so I can listen to it in iTunes. The only reason a license would be needed is if I want to distribute that MP3--that act of distribution is what the copyright monopoly restricts me from doing. In order to bind non-distributors to a license, one of two things needs to happen: 1) the non-distributor must be convinced to enter a long-term, ongoing, probably paying relationship with an upriver creator; without this sort of long-term relationship, what you have is a purchase, not a license, and sellers are very limited in the ways in which they can restrict what purchasers do with the things they've purchased (even if, in this case, the "purchase" is at no cost). That is, you can't just call it a license; that's what EULA writers are doing. Even if you call it a license, if it looks like a purchase it is really a purchase. 2) EULAs have to be made enforceable as licenses on the end user; as I understand it there are a few states in the United States that have made EULAs enforceable, but most have not. I would hope that the FSF does not want to encourage making EULAs enforceable. That's a very dangerous road to go down. If an end user agreement from the FSF can force people to make their modifications public, what is stopping someone like Microsoft to force people not to say bad things about Microsoft in their EULA? (Believe it or not that clause is or has been in their EULA; it just isn't enforceable.) There is no end to the kinds of things EULAs will try to enforce on end users if they become enforceable.
