Yeah, the GNU/Linux naming issue is one thing I never understood. It seems very petty to me, arguing over credit. I wish his attitude were "The good is done, great! Let's do more." :)
But maybe that's because I've never worked on anything as hard as Stallman did on GNU. Still, it seems impolite.
RMS doesn't seem to really care that much about credit, per se. Certainly, he believes it right and proper that GNU receive credit for what GNU is and has done. But more importantly, if GNU is not part of the name of the system, then users will be prone to forget about GNU, and in so doing forget about (or never even become aware of) the issues pertaining to software freedom.
