>>3700612The Hololive girls have no say in the matter. Collabs are set up through managers.
Regardless, Hololive typically works within its own ecosystem. They don't work with other vtubers. They don't feel the need to. The reason for a collab is to try and exchange some audience members. For it to be mutually beneficial, both sides must have similar audience numbers. Hololive is already the biggest. Collabing with other vtubers would only draw their own audience away from them.
