Ah yes, I'm pretty sure the private repo part is what interest microsoft. And integrating github in the VSStudio suite is certainly something they have in mind. And they may probably do the same for VSCode. Even for the free part probably. The objective beeing converting as much company as possible to the VSStudio/github ecosystem. And make more benefit with it. I'm pretty sure MS bought github for profit, not to help the opensource world. But that doesn't mean the opensource part of github is doomed, that is just my point.
