Right, they were just using the data that Google was already taking. But now on GrapheneOS, I'm not giving Google that information anymore, or at least trying not to. I even still play Pokemon Go a bit, but I've turned off the ActiveSync stuff that tracks me when I am not actively playing the game.

I'm going to have to bite the bullet and fully degoogle myself eventually. The only concern I have with graphene is it's recommended phone is pixel, made by the very people I want to escape. What kind of backdoors are there in the chips? That concerns me. I know there's probably other options out there, and I need to explore.
The main problem is apathy - I didn't switch to Nostr fully till I got nuked on the dead bird app. Without an over riding emotional response change comes slowly.
