You think so?I don't think corporation brands mean much unless you belong to the big 3.
There are dozens of indie vtubers debuting every day and nearly all of them will struggle to get beyond one-view numbers. Even a small corpo like Phase Connect gave it's Gen 2 streamers hundreds, if not thousands of views on their debuts, and it's only going to be bigger when Fishman does Gen 3 or Phase Invaders 2 with how much Phase Connect is growing.
Even small corpo brands are a draw and have some meaning, both to the type of content you expect but also a general level of quality and polish.
