F-Droid doesn't enroll as device administrator on your phone. I think Microsoft could easily pull that off if they wanted to which would let them push updates and manage applications the way Google does. My workplace already basically runs BYOD devices through some Microsoft Azure management thing.

There is an extra thing you can do to make fdroid admin but it requires root. It does allow auto updates though.
