Every rumor is true, huh.
Despite Brave's business strategy of just buying their way to mediocrity, their current EN groups are at least competently managed and given that Idol has gone from crisis to crisis, management like V4M's would be a vast improvement.
On the en side, I would agree, but they have a money printer on the JP side, so they can afford to grow like this, so I can't critique their strategy too much. TBH, the biggest thing holding EN Vtuber Orgs back right now is Management capability.
If you have enough funds, you can buy yourself into a permanently profitable position. It's just a question of how much money it took to get there. They're definitely here to stay, or at least have the funds to get in the game.
