I agree, after making an account with the button, you are stuck with Apple forever. If the sign in id buttons are not cross platform, thats abusive lock-in.
The create account button might not be available on android apps, but hopefully the sign in sso buttons works. Maybe identity portability will become law someday, like cell number portability and being able to change your address at the post office.
