If, in the likely event that Linus, the commercial distros, and the heavily-invested-into-Linux corporations stick with v2 while Debian and FSF go to 3, that, my friends, is the long-anticipated fork of Linux.
And if, in the likely event that development efforts cross the boundaries of the fork, then the inevitable accusations of one side will lead to challenges of the legal terms supporting the other, and the GPL will finally receive it's day in court. In this, it will likely faire better than expected, but not well enough to protect the current status-quo: where the license is respected for its intent out of a sense of community, and its legally-shakier provisions are ignored.
Stallman is proof that if you follow a liberal (who is right in spite of himself) even to the gates of paradise, he will complain about the humidity and torpedo the whole affair.
Oh well. Maybe it's time to start checking out NetBSD...
I don't know if they could do that. Linus controls the license for at least most of Linux, and Linux doesn't have the "or future version of the GPL" in it, so others can't exactly change the license without his permission.
