I mean, if you're using GrapheneOS, you're probably already smart enough to not use microG at all if privacy concerns you, or use their sandboxed Google Play if you really need that.

Joke's on you, I use shelter in my GrapheneOS so that there are only google services used in apps where it's literally necessary

I looked at graphene and then realized that the Gov and Evil Corp cared I would be fucked anyway. I really used to care about privacy, but truthfully as a middle aged, slightly bolding bloke, I am boring. I mean, what do I have to hide? Now if I was an transexual furry, then yeah, maybe Graphene would be my mobile OS. And maybe that is why I should install it: to create noise for marginalized communities. Fuck. I think I just convinced myself to try it.
