Seriously though, I agree. Stallman here seems to be adopting almost a religious argument, not a pragmatic one. He even announces a refusal to use Skype because it's not free software. If he prioritizes freedom over everything else, then more power to him, but to me talking about who "wins" and "loses" on some kind of arbitrary scale of freedom does not make a compelling case against the use of excellent tools like Clang/LLVM.
