Linux is a class of operating systems which use the Linux kernel. Referring to Linux as an OS, is a perfectly fine thing to generically mean 'an OS which uses Linux as a kernel' and has an agreed common meaning.

Almost no Operating System is precisely GNU/Linux - most have vim, an X server, GNOME or KDE, 7zip etc. And the argument that GNU is a more principal argument is incorrect.

Uhm, you're saying GNOME, the GNU Network Object Model Environment, isn't GNU?

[richardwhiuk]

GNOME is developed by the GNOME project, which as far as I can tell isn't actually part of the FSF.

I don't considered everything licensed under the GNU license, or formerly associated with the GNU project / FSF to be 'GNU'.
