TL;DR
- Efforts like Graphene OS face increasing pressure from apps that refuse to run on non-standard Android.
- The custom ROM project characterizes Google’s approach to device attestation as incomplete and flawed.
- Graphene OS is prepared to take legal action if Google won’t let it pass Play Integrity checks.
Ironically, if Graphene would succeed, it would lead to a system that’s every bit as locked down as a manufacturer’s Android. GrapheneOS would also not allow you to have root etc.
IMO Graphene wants a place at the big player table. They’re not in it for user freedoms.
