The real issue is that Google stores your passwords in plaintext. That’s why they survive a password reset, or apparently now can be shared with others. Proton and Bitwarden encrypt your passwords so that nobody but you can access them, or at least in the case of Bitwarden, you can share with other users using pre-shared keys.
I don’t trust them in general but I’m certain Google doesn’t use my passwords for advertising.
