Do the Women on the Female Dating Strategy to 4B Movement Pipeline Never Question Why the "Handbook" by Definition Didn't Work for Them?

There are a large amount of women on Reddit who were FDS denizens a half decade ago who have now gone 4B meaning no dating, sex, children or marriage with men. Some of them even regularly comment on this sub.

My question is, this. The whole original claim of FDS (which it still sometimes makes in its non Reddit incarnation) was that following the FDS handbook would bring women dating success and healthy relationships. But many of those same former FDS followers went 4B over the last year citing lack of dating success or healthy relationships. So don't these women question the fact that the FDS handbook fell short of its original promise to women?
