alt Hacker NewsGraphene is not a kind of Android. It doesn't even advertise itself as such:

GrapheneOS is obviously an Android distribution, but I suspect trademarks mean they have to be careful about how they describe it.
GrapheneOS is based on the Android Open Source Project and retains near perfect android app compatibility. It cannot call itself android for legal reasons, but the legal definition does not affect its app compatibility.
Tools such as play integrity are illegal. Using anticompetitive and monopolistic tools is not the right of application developers.
