Windows is still doing a lot of bullshit with ads in the start menu and forced updates. A bunch of their open source stuff which has included spyware has been less than upfront about including spyware.
I think what happened to Skype is a case in point. It doesn't matter who's running Microsoft, after that disaster I don't think anyone's going to be trusting them.
Skype has basically become unusable for professional communication. It’s getting worse with every update. I kind of expect the same for Github then. That’s my concern.
