Well, let Stallman fork it and his own code. LOL

Well, we need the compiler, gcc. The Linux kernel will not compile with any other compiler. But fortunately we can continue to use the existing compiler, under its existing GPLv2 license. Compilers are constantly changing, as are most other large, interesting code bases. So unfortunately, if critical changes, such as new instruction set architectures, are added under GPLv3, it could get "interesting."

But, yeah, interesting images of Stallman and forks have passed through the minds of several of us.
