Most of the subs that chronicled it are currently shuttered.
Specifically, there has always been a contingent of shitheads on metafilter who dislike wrongspeak, and REALLY want to steer the site. They occasionally get thumped and dumped, but most of the time they flounce off, in site parlance "buttoning"
Matthowie, the original site owner got tired of running the site and sold it to Cortex, Josh Millard

People constantly got mad because Cortex would mix it up with shitheads while wearing his moderator hat, kind of like how null gets tired of shitheads and bounces them.
This drew heavy criticism from the contingent (they call themselves the cabal)
One thing the cabal constantly demands is that metafilter become a nonprofit 501 c (I don't actually understand that shit, but the actual staff are extremely hostile to the suggestion)
They managed to bully cortex into a "steering committee" and "BIPOC board" where they pay minorities to tell them how to run the site.
Cortex absolutely lost his shit over a trans wanting their entire comment history being nuked from the site and was all "That is not something we offer, and we do not want to do that"
Cue 3000+ comments from people not liking that position.
Eventually he got sick of the site, but always said how he would "preserve" it. He ended up selling the site to an Ex moderator who still posted a lot on the site, Jessamyn. Jessamyn is a library nerd.
After taking over, Jessamyn has been a mostly hands off site leader, trying to keep the site afloat. The lawyers for the site told her to absolutely stop the "Steering committee" and so it was disbanded. Apparently the BIPOC board is ongoing.
