We've wanted to make this change for the last 18 months, but needed our Enterprise business to be big enough to enable the free use of GitHub by the rest of the world. I'm happy to say that it's grown dramatically in the last year, and so we're able to make GitHub free for teams that don't need Enterprise features.
We also retained our Team pricing plan for people who need email support (and a couple of other features like code owners).
In general we think that every developer on earth should be able to use GitHub for their work, and so it is great to remove price as a barrier.
I can't. Does GitHub really have nothing better to do than to play nanny cop because I used a naughty word in my code? Are brainfuck interpreters now off-limits? How about drivers for teledildonics hardware? Or libraries specifically for detecting and filtering swear words? Or maybe I just want to vent a bit in a comment every once in awhile because of some annoyance with the language or target platform or problem to be solved?
Fuck that and the horse it rode in on. We're all adults here (well, or possibly teenagers, but let's face it: they've probably already heard much worse at school).
Not that this seems like the real reason why SS13 got nuked anyway; if GitHub really has some kind of anti-profanity rule, they're doing a real bang-up job of consistently enforcing it: https://github.com/search?q=shit / https://github.com/search?q=piss / https://github.com/search?q=fuck / https://github.com/search?q=cunt / https://github.com/search?q=cocksucker / https://github.com/search?q=motherfucker / https://github.com/search?q=tits
