While that's better than not learning from the mistakes of the past, how can you possibly believe that there are no new mistakes to be made, or opportunities to miss out on. GitHub's major selling point is mindshare/popularity, and git by default makes moving to another git hosting service relatively trivial. Yes, there are issues to transfer, but it's nowhere near as difficult as in the days of SVN, where you'd need to have shell access to dump the repo, or hope it was a modern enough svn version to support remote dumps (and that they didn't time out).
