@nprofile1q... It's not legitimate. The companies involved in it have atrocious security for their devices. They've created a system to permit using their own products while forbidding others. It's inherently not going to be neutral or fair. GrapheneOS isn't simply not going to participate but is going to actively fight against it. We're determining the best way to do that and one approach under consideration is a library banning any OS including Unified Attestation which we'll promote apps using.
