Feldenkrais might not be a cult as defined by Rick Ross and others. But it looks like there are many allegations of sexual harassment and abuse as outlined by this website:
I have done a fair amount of Feldenkrais myself. And I enjoy it. It's kind of like a very gentle and effective Yoga. And I always feel relaxed and centered after doing it. Even so, the allegations of harassment towards women from some of the "higher-ups" are very concerning to me. It looks like some private forums talk about some of the incidents, but no mention has been made publically as far as I can tell.
