@oyam I should say that I understand that forcing a less secure password recipe on a user does harm. Even in the case I suggested, where the site "advertised" both simple and complex recommended recipes, the user should always have a choice of making and using a complex recipe for thier own passwords.

The key to my question comes from the advertisement, the presentation of the recommended recipe during password creation as (and ignore this charged desrcipton) fake news for the potential hacks, misleading them to stick to more simple recipe algorithms -- wasting time on many many cracking attempts, because using a simple recipe algorithm on an even one bit more complex actual recipe yields zero successes over the entire run.
