Since its inception there's been fear about Mono being a dangerous platform to develop on because Microsoft might try to torpedo the project at any moment. This is far from the first time that Microsoft has publicly given the Mono project their blessing, but one that comes in the form of a business partnership is still nice in that it might help cut through the FUD just a little bit more.
I suspect Azure will continue to use Github; moving would disrupt a lot of developers.
