Eh, the whole thing is mostly just a weird takeover attempt by Jax Bryk etc, and even has some weird crossover silliness with the Eliezer Yudkowsky/SlateStarCodex "rationality" peeps.
Basically there's a few girls with a strong interest in tech and gaming, who learned to feign sexual interest in exchange for attention / a foot in the door, then cry sexual assault as soon as they secure their position, then repeat the process over and over again within the same communities. And as long as you have people willing to white knight that can't imagine ever being accused themselves, those white knights will continue to fall for it, and continue to get metoo'd, until there's no one left to take down.
This works especially well because usually the "white knight" male feminist supporter ally schtick is usually just a front for getting a little rapey anyways, so not much smoke has to be produced to draw attention to the existing fires.
