Same thing that happened to a lot of the earlier online "dissident communities." Trump.

When 2016 happened, a lot of the more realistic elements of the Manosphere got absorbed into the broader space that was the dissident right. As soon as someone who was (nominally at least) openly opposed to the prevailing leftist narrative paradigm actually gained political power, it became very difficult to be a part of any anti-left space without becoming fully absorbed into the political and societal narratives of the larger dissident space. Niche markets like the "Manosphere" couldn't just stay in their one narrow lane because so many people involved in it had broader political interests.

A significant portion of the group calling themselves MRAs were always leftists, who genuinely thought it would be possible to change the way society looks at men without abandoning their progressive politics or their simping. Most of them are just plain leftists now: women's approval was just too important for them to continue participating in a space that garnered so much societal disapproval. When Trump happened, a lot of them just couldn't deal with it for the same reason a lot of women, even nominally right wing women, couldn't deal with it: because the language Trump used was too mean.

Other groups always had limited growth potential. MGTOW was never going to be very big, because there's only a small proportion of men who are ever going to be psychologically able or willing to leave the reservation and just choose to live without women. Having a family is just too important to most men, and that's probably a good thing.

TRP and PUA types were always very juvenile, comprised of a few older grifters like Roosh and others who were just in it for the money, and a large number of very young men and teenagers who worshiped the ground they walked on. That was never going to last longer than it took for those guys to just grow up a bit.

As far as specific creators: HBR is still producing content that only a few hundred people watch. Some MGTOW YouTubers are still producing content, guys like Sandman (cringe), Independent Man and Thinking Ape (less cringe), but really interesting guys like Colttaine appear to have mostly disappeared. The MGTOW win still has links to some blogs.
