Just like facebook or google can block your account and prevent you from accessing all those logins you linked ever again.

So you better log in with your own email, but of the 3, I’d rather pick Apple as the lesser evil!

Apple isn't just holding your authentication like Google login, but Apple is also exclusively holding your contact information. This means Apple has a sore authority to completely cut your access to your users: you have zero means to reconnect to them. This is different from other authentication methods where the provider does get an email address where they can use that communication medium to bypass the platform if needed.
