Re: It could have some benefits...
In the last few years, many open source projects have given up their own Subversion / Git repository and moved to Github or at least mirror their repo to Github to conquer new ground and find more developer.
A big problem is Google. The Google search is especially bad at finding Subversion or Git repositories hosted elsewhere. Google is only good nowadays finding code on Github. Google Code Search was great, but it is no more (dead like many great Google (search) products).
Yes, open source should move away from Github NOW. Host your repository on your server, and just mirror your repo (read-only with no "Issues" tab enabled) to Github. And cut the string completely with Github, in worst case, when M$ buys Github.
