You clearly don't understand how social logins work, nor their benefits for users and site owners. Both of your assertions are wrong, and both "bad" things are exactly the opposite. You don't get anything beyond what you ask for AND are granted access to by the user. FB login gives email and name AFAIK, but you can ask for lots of other stuff and be denied. Google defaults to email, not sure about name, and has separate requests and grants for any additional information. They don't have nearly as much of a profile as FB does, but can give address and some other details. Apparently Apple doesn't even provide a real email, so that seems even better for "collecting [your] personal information" than using... your personal email address! Social login is much better than storing passwords in any form (plaintext, encrypted, hashed), and gives both the user and site owner the benefit of FAANG security.
