I tried to switch to graphene for similar reasons to you. It just wasn’t viable, as you’re discovering.
And if you want to even attempt to have a modern smartphone experience, you’re logging into Google account, which is an “out of the frying pan, into the fire” move.
For now, Apple is still the best in a bad situation, and at least for now they aren't primarily an ad company.
I am glad about the Graphene+Motorola partnership though, it always felt ironic to me to have to give Google money to completely escape Google.
