I have never used a MS account for local login but it sounds to me like it just leads to people using insecure passwords for publicly reachable accounts because they don’t want to type a long password every time logging into their computer.

And backdoored encryption is just as bad as unencrypted, maybe worse, since it lulls you into a false sense of security.
