Still, you are stopping the extraction of analytics, which probably bring Google the much more revenue over the longer term, and it is not possible to disable on regular Android phones.

Remember that on every certified Google Android phone, Google Play Services runs with system-level privileges. On GrapheneOS, it is sandboxed like pretty much any other app (if you choose to install Play Services) and you can make it 'blind' by revoking most privileges.

Same for Pixel Camera, etc., I just block network access.
