As sad as Fauna's presumed graduation is, there are still many vtubers that find a lot of use from a corporation, especially Hololive. The Hololive girls get to participate in the best concerts in the industry, get support in training for those concerts, are part of well-prepped and well-funded collaborative events, got far bigger audiences and incomes while at Hololive, as well as a lot of management support.
We don't need to doompost about the existence of corpos just because Fauna has decided her time is over at Hololive.
