I find the rapidly increasing collapse of the 'monetize downloads' business model quite refreshing. I hope Github has enough revenue to not have to revert to things like this in the future.
They don't suck and we're enormously happy. As the sysadmin whose job it would otherwise be to manage Gitorious or Gitlab locally, I am delighted to be able to outsource this task.
So yeah, I'm extrapolating from anecdote but for the moment I think their prospects of continued payment for services are pretty good.
