I think Embrace Extend Extinguish applies perfectly here, but with respect to git and not github. Github has already become the way that a vast majority of people interact with git, and it already has lock-in potential with the value-added features it implements: I've worked at companies which use github almost exclusively for project management and issue tracking, and it would be a huge expensive burden for them to change to something else.

Owning GitHub puts Microsoft in an excellent position to advantage their own products, and disadvantage competitors. Given Microsoft's history, I can not see it as anything other than foolish to assume this time they are going to act altruistically.
