meowijuana Though I have not seen contract terms recently, I believe Google enforces a long list of requirements on platforms they certify, including things many people here would not want, such as the full suite of Google apps being permanently installed.
So, sure, Motorola could ship an OS certified by Google that would pass Play Integrity... I think they already do! People who want that can get it now; people who want that plus some security and privacy enhancements that Google is neutral on may well be able to get that as part of a collaboration with GrapheneOS.
But for the foreseeable future I believe people who want a "de-Googled" or even "de-bloated" OS will not find Google certifying one.
