As @davatron5000 says, I don't like playing cat and mouse with my privacy. https://daverupert.com/2018/04/dave-went-android/ At the same time, I'd prefer to run open-source software rather than iOS. And I've used Android since the HTC Dream.
But using Android without Google apps is just *so* hard. Not only do I have to invoke weird terminal sorcery every six months, but the damn thing doesn't even work very well – I haven't had working push notifications or GPS in a year. Time to throw in the towel?
