There is also a better way of commenting, like providing an alternative or engaging with the substance. A modern site not working with password managers might in fact be moronic to many, especially those on HN.
It's a pet peeve of mine when applications have stupid password requirements. It's an incredibly basic thing to get right. If you can't get that right, good luck with the rest of the application.
The only exception to this is if someone is trying to use outrageously long vaultwarden passwords (eg 100 characters) as that can technically break some ciphers, and doesn't provide meaningful security.
