Well, the assumption that I'm perpetuating it is on them then. I could have said "why don't you setup a git repo", but then again the easiest way of doing this would be via Github - which is a low barrier to entry.
Or they could use any of the other git repo hosting services out there. But, in my experience, GitHub is the easiest to use. A bit silly to downvote for that reason though, if that's the case.
I don't think Github is evil (yet). The fast and easy way to delete an account there is too transparent. They don't have also a strong competitor, neither weak points to be explored by a new player. We'll enjoy the status quo for some time: Google, Facebook, Microsoft all gave in to Github.
BitBucket is a good underdog IMHO. I use it for all my private projects or stuff I don't want out in the open just yet since they offer unlimited free private repositories.
It's rather nice to be honest.
They support Mercurial if you're into that as well.
