Disney owning any attribute of any VTuber in any capacity will be the funniest way to kill any probable success that VTuber could have. Pairing a conglomerate that literally is incapable of permitting something to so much as twitch without yanking the leash with a medium filled to the brim with talents who thrive at their best by being as off-leash as possible with a ToS gate to keep them vaguely reined-in is a match made in hell. I'd feel serious remorse for whatever talent got signed under Disney's branch, but I would feel a sense of schadenfreude to see them bumble their way into the industry with some zombie that can't do anything or say anything off-color without them threatening to fire them.
