Check out LineageOS as well, the phone compatibility is way bigger (you may not have the security hardening of GrapheneOS but you will also have a much longer support).

Yeah same, they also choose to drop support for phones as soon as official support drops which is a bit dumb (most firmware are feature complete and don’t have security issue, on the other hand not delivering OS updates with security fixes is definitly dangerous).

I much prefer the philosophy of LineageOS: you don’t want to throw away your 10 years old phone? Just put the latest android version on it and go on!!

Also with open firmware (apparently this doesn’t have any) there is always the question of camera DRM.

Did Grapheneos sell itself out?

good, but maybe it’s too little too late ? but still, competition is always a good thing to have
