Degooglized Android
I'm sure this is one of Google's biggest fears - what if Microsoft decides to go all-in with Android, and builds a version that replaces Google Search with Bing, GMail with Outlook 365, and so forth? If Windows 10 Mobile flops, and Microsoft gives up on Windows on phones, they might go this route.
Microsoft would probably not care if they made any money on this, as it would hurt one of their biggest competitors. Might also hurt Apple as far as getting iOS in the enterprise, since this Microsoft Android OS would likely work better with Windows services and have better enterprise manageability.
This isn't going to fix the problem with Android updates (which really isn't Google's fault, no one but Apple and maybe Samsung has enough clout with carriers to keep full software control) but a major security incident on Google Android could really hurt its image and help Microsoft's version.
