Oh, wow. Yes, you did.
Ubuntu had its critics from the beginning, of course, but so does every Linux distro – that’s why there’s so many of them. Ubuntu made a point of appealing to novice Linux users, which was generally considered a good idea, though it meant that Ubuntu was associated with novice Linux users.
There were two big blowouts with Ubuntu a few years ago, however. There was the introduction of the widely unpopular Unity desktop interface, and Mark Shuttleworth (the CEO of Canonical, which develops Ubuntu) responded to complaints from the Ubuntu community with what amounted to, “We’re professionals, so shut up”.
Most relevant to Feminist Hacker Barbie, though, was an episode in which Shuttleworth said in a public speech that Linux is “hard to explain to girls”, which drew a lot of criticism, particularly from Geek Feminism; Shuttleworth made a point of refusing to apologize.
I’d guess Feminist Hacker Barbie would use Debian or OpenBSD. (Personally, my favorite Linux distribution is Fedora, but I don’t think Feminist Hacker Barbie would use it, for one obvious reason.)
