Some people are saying it's Vox because of the language. That and Vox has talked about the market becoming stagnant. He's just pretentious though and has admitted to not watching other vtubers which is.. a choice lol.
And maybe I'm reading it wrong, but does this article say anything of substance? It's basically like "Corpos can restrict their talents and make the scene stagnate so maybe switch it up." Also it's hilarious that they mentioned Idol and not Vshojo, the face of Talent Freedom.
