You know, I’ve tight about this, and I think the whole "former fujos become enbies, fakebois, and rabid antis" thing is just a tad overblown. At least based on what I’ve seen these days.
I don’t think those shippers actually went anywhere, it’s just that the slang they used simply changed. Gay male shipping content is still the majority in most fan bases, most of the cliches associated with yaoi shippers still exist under different labels, and most of the ones producing that content still identify as women. They just don’t call themselves fujoshis or use the old lingo like "seme/uke" and shit. Weirdly, it seems like the ones who go full anti-fujoshi and/or fakeboi are either bitter women in their 30s and the impressionable youth that get caught up in their antics, or the ones who tend to be into the shit that’s considering especially un-kosher in woke circles like sissyfication or crossdressing - lolcows like Yaoi Goddess Keale and Julien Myers come to mind.
If anything the bigger friction in fan communities these days seem to be self-appointed snot-nosed kids bleating to random fan artists that they’re predators and hags for the crime of drawing fanart while being over 20 - even when the fanart is for something that was always meant for adults.
