I noticed absolutely no change in Github's product after the Microsoft news, and I'm 99% sure there will be no appreciable change after this news settles. I'm 100% sure that people are going to freak out and waste their time migrating to BitBucket or GitLab for the wrong reasons. As a Github user, there are a few things Github does that makes me unhappy, like not hyperlinking static text when they should, but who they get in bed with is not one of them.
