I'll forego using colorful language because as I've made it clear, I find it really hard to hate anyone or anything, but here's a more factual rundown of everything that's happening.
Vshojo was a group that was started by TheGunRun and MowTenDoo, and contains basically a who's who of English Vtubers from the Twitch scene along with some relative unknowns. As for who these two chucklefucks are, TheGunRun is Justin, aka the Justin.tv Justin. Co-founder of Twitch. I'm not sure what he's been up to now but I'm pretty sure he's handed off Twitch long ago and is no longer in any sort of managerial position. MowTenDoo is a programmer and video editor who supposedly made a bunch of games nobody heard about, and is more famous for his song edits on Youtube; Blend W and Weed La Weed are his most popular ones but by far not his only recognized works.
As for who they recruited: ProjektMelody, IronMouse, SilverVale, Nyanners are their main draws; I wouldn't be surprised if this agency was their idea and they only really did it because they're fucking stupid when it comes to actually running a business (most streamers are) and needed that level of protection in case something like Mel's bullshit ever happens again. The other 3 recruits are Zentreya (there's enough here on her that you can make your own decision), Froot (actually BSApricot, a prominent artist for the main 4) and Hajime Hime (Gigguk's fiancee Sydsnap). The reason people here are looking at this group and waiting for an implosion is because Zen and Silver are borderline lolcows in their own right. Mel just has a lot of shit thrown at her and is dumb as a box of rocks, Nyanners is a chan traitor, and Mouse is honestly a very sweet person whose life is fucking rough, to put it mildly, and probably deserves success more than anyone else. I don't think anyone has anything on Froot and good fucking luck trying to get anything out of Syd, that woman is fucking insane as it is but not necessarily a lolcow.
Edit: In possibly the weirdest fucking brand deal ever made, Amelia did a Bookwalker sponsored stream to read a trashy isekai light novel. If I see Calli do a sponsored deal with Raid Shadow Legends I'm fucking out.
