out of the 3 (google, fb , and apple) , having a fake FB profile is probably the best for my privacy. While FB may have tracked me they probably dont know my real name, while for apple it's mandatory, and most people probably have used their CC details with google at some point, plus these companies have my realtime location data as well. None of these systems are really private and it is a lie to tell our users that it is. That said, SSO logins are replacements for passwords, not usernames. You should always ask users for their email afterwards if you don't want to be bound to the service's whims who may decide to block you from their service or impose weird terms in the future, like how FB requires various forms of verification / interrogation to continue using their platform.
