It's actually way worse. Most vtubers aren't actually using their natural voice. Some just speak in a higher register than usual but a LOT (even ones you might not expect) are full on using a character voice. What they're doing is less like radio personality work and more like voice actor work. Professional voice actors (and singers) do a lot of stuff to manage their vocal cord health during long recording sessions like taking breaks, doing special vocal tract exercises (SOVTE), and other stuff. They also take precautions and stuff when dealing with scenes that require screams or other straining performances.
Vtubers, on the other hand, will stream non-stop for hours with no breaks (even no small ones because silence is bad), have regular screaming/yelling/laughing fits/etc..., and they'll often do this even if they're sick or have been having voice strain issues. Add to this the gimmick streams like how they'll do those insanely long karaoke streams where they'll sing the same song over and over

or how they'll play through entire games where they voice all the characters. Then add reading super chats on top of that. It's actually an incredible amount of strain go regularly put on your vocal cords.
I'd imagine the situation is worse for indie vtubers but who knows, maybe corpo vtubers aren't getting much in the way of voice health education/support.
