I see lots of people arguing that microsoft's open source efforts are in good faith.
I don't believe that is possible, and I won't believe that is possible until microsoft releases critical components of their software under the (a)gpl version 3 or later.
Microsoft spent years operating under a model of Embrace Extend Extinguish, and we have no reason to believe that they have changed.
Microsoft is your enemy. The fact that they are embracing a thing you love should terrify you.
