Judging by the comments we get on ProgrammableWeb and that I get in inbox, it seems like a toss up with developers that were once loyal to Microsoft. Some are so die hard that if you even suggest the idea of a future whereby Microsoft has challenges, they'd just as soon slit your throat. Others are clearly spotting greener pastures elsewhere and have decided its time to move on. But, while Satya Nadella has the challenge of competing forces to reconcile (budget vs. the long game), he seems to be keeping the best interests of developers in mind, or at least trying to.
