The great thing about microG is that you can configure everything in it that communicates somehow with external services. So for instance you can disable Google Cloud Messaging (I think it's even disabled by default), or enable it only when you need it, or configure it so only one app can use it, etc. The same with GPS augmentation - backends for it are switchable, so you can use Google, Apple, Mozilla or even offline database for that. I'm glad microG exists, I use it on my one Android device I keep for testing Android ports of my software and for occasional emergency situations (like having to use mobile bank app or get some transport data that's very helpfully only available as a mobile app for platforms I don't want to use on my main device). Otherwise I just keep using Nokia N900, which replaced my old Openmoko Neo Freerunner. I'm waiting for my preordered Neo900, Librem 5 and Pyra.
