I'm gonna share this, and add onto it - I know most of us have probably seen parts if not most of the awful Pippa/Merry stream (and his subsequent "joke" about her with the Nijis), but I personally can attest that he is probably one of the last people who should be managing a talent agency.
Merry's biggest problem, in spite of what he'd like you to believe, is his arrogance. He has an overinflated ego due to the success of his comics, and as a result has decided to do his best to protect that ego, even when people just don't like him for one reason or another. I'm really sad people don't properly document his menhera moments more often, but I don't really blame people not wanting to follow him (even if he is slightly lolcow-ish) just because his content is far too annoying to dredge through for the funny stuff.
The reality is that Merry is basically an Elon Musk - somebody who sees talented people and wants a piece of their success, and then credits it all to himself (he'll pretend like he doesn't do this, but his entire brand being named after his username is peak attention-whoring). He'll say it's because he's "such a good writer", but most of the appeal of his comics is the excellent art done by far better people than himself. And also like Elon Musk, he is really just a guy who throws money around and chases trends, while never truly having a personality of his own. This desire to be seen as one of the beautiful people is clearly expressed in him making a vtuber agency and choosing to be one of the talents himself. It's missing the point of an agency in the first place. I can only forsee this going badly, as his own desperation for validation will make him crack sooner or later.
