call to action-quote from the link above:
In addition to leaving feedback for these apps on the Play Store, file support requests and leave feedback on third party review sites. Ask them to stop banning GrapheneOS and explain that it's a much more secure OS than what they permit which does not lose any of the standard security model. Explain that they can use the hardware key attestation API to verify that a device is running GrapheneOS to permit it alongside an OS licensing Google apps as they do with the Play Integrity API already. Make sure to push back against false claims that it has something to do with compatibility or security issues. The only reason they aren't permitting it is because we do not license Google Mobile Services (GMS) and these apps are enforcing Google's business interests rather than security.
