But no one should use sign in with google.

Are you saying that it's 100% garanteed optional in all situations? It has no power to be used to control or even coerce you or discriminate against you or build a profile and track you which can be used at a later date by a different party when a new political wind decides it finds you inconvenient? I find all of that hard to believe while still performing the convenience function let alone any legitimate law enforcement function.
