I'll get hate for saying this but fuck it, truth is truth and RMS burnt a LOT of bridges with GPL V3 so I wouldn't be surprised to see more devs moving from GCC to LLVM and Clang.
What RMS and his fans just seem to refuse to accept is a simple little bit of reality which is thus...this ain't 1979 anymore, no matter how many times RMS calls everyone "hackers" like he's at a computer club meting. The chips, the designs...we are talking about INSANE complexity folks, it is just not something "a couple of guys banging away in their basement" is gonna be able to do. What you have to have is dozens of highly skilled, highly trained guys working on this stuff 8-12 hours a day every day...the requires funds folks, no way you can get around that.
What does that have to do with RMS giving corps the bird with GPL V3? Simple...where do you think ALL that money was coming from? Donations by individuals? Nope that was all being paid for by corps whom RMS made clear aren't welcome round here anymore. with GPL V2 you had kind of a "wink wink" with the corps while GPL V3 has made sure that you had better be a GPLed company if you want anything to do with GPL V3 code. This is why Google has a "No GPL V3" rule with ChromeOS and Android, and I have no doubt you'll be seeing money dry up for projects like GCC, simply because companies will be afraid to touch it.
At the end of the day encouraging corps to open their code is fine, flipping them the bird if they refuse to go GPL? Not the smartest thing. We should be able to tell within the next year whether all the money is gonna go to GCC or LLVM/Clang, I personally think it'll be the latter.
