If Microsoft behaves as they have done in the past, this is what will happen:
1. Make Node run on top of Chakra [x]
2. Give Chakra non-standard features and sell communities on them while pointing out to dissenters that the extensions are open source []
3. Gradually allow open source work on the product to die and commercialize it []
Microsoft has lost a lot of people's trust. My grandfather used to tell me that trust is hard to earn and easy to lose. Once trust is lost, it's even tougher to earn back. It's going to take some convincing on their end if they want developers to trust them. It doesn't __matter__ if they appear to act more ethically than their competitors, that's not how trust works, and it won't convince a lot of people that have watched Microsoft for a while that they've suddenly changed their ways.
EDIT: funny this is being downvoted considering eee was an actual strategy Microsoft has historically employed according to the US Justice Department. This isn't even conspiracy theory stuff -- this is real life. Those who don't study history are doomed to repeat it.
