There is also keepass, which you can sync with whatever free cloud storage you want. It might not be the nicest password manager you can use, but you can always use it for free.
Bitwardens free tier is also generous enough that a lot of people won't have to pay
KeePassXC has been repeatedly threatened with blacklisting by the WebAuthn alliance. Once for allowing exports of passkeys, once for not requiring reauthentication of an already unlocked vault when providing a passkey.
Seems like the existence of keypass does not support the argument made in the OP.
