So the FSF's (read: Stallman's) opinion is that not only should a distro ship with only 100% free software, that users should be actively prevented/discouraged from installing "non-free" software onto their computers?
This is why most people think he's a fucking crackpot.
It's interesting to see that in the gnewsense wikipedia page that Debian considers some of the GNU documentation to be non-free because their license allows an author to say "you are not allowed to modify this part of the manual", which is somewhat against the spirit of the FSF's opinion on code.
