And in the "GNU/Linux" corner
RMS calls it "GNU/Linux" -- and he and his sycophants insist you should, too!
The Free Software Foundation (Hey, that's RMS's baby, right?) calls it "GNU/Linux".
Trisquel? "GNU/Linux". RMS uses this.
The GNU Project? "Gnu/Linux". Of course. Why not?
There are more. I don't run with that crowd, so I don't know about most of them.
