With only GNU, there wouldn't be any either. So what? There's good things to be said about the GNU project, but they are an example of an approach that's not the best way; the cathedral approach.

And you're free to drop the ridiculousness. You say "what you probably call linux and free software"; if you want to lecture people on nomenclature, I think you should find a shift key. (And it wouldn't hurt to make sure you know what they call things. Presumptive ad-hom has almost as much potential to make the wielder look foolish as failure to capitalize.)
