And Ubuntu is? Last I checked Stallman hated Ubuntu, and told everyone to stop using it.
It's still the GNU userland on top of the Linux kernel, whether he likes it or not.
This is the one thing I don't understand about the GNU/Linux thing. Doesn't calling it GNU/Linux imply that it is derived from the GNU/FSF philosophy? To me it would make sense if another term can be coined to refer to systems that have a GNU base, yet go against GNU's goals, yet still credit the GNU project for its contributions. (I hope I'm not re-igniting the bad parts of the GNU/Linux debate).
Ubuntu is certainly what Stallman would call GNU/Linux. Just try to call it otherwise in his presense. ;)
Ubuntu, along with Debian, Fedora, and just about every major distro have always been on RMS's "not recommended" list.
