It's not a problem if they think of themselves as VAs and their fans think of them as VAs and superchats/memberships are like paying for anime. But the types of women who 1) do gfe baiting and aren't entertaining but then reee when their cultivated audience of simps doesn't like them flirting with guys 2) the kinds of girls who unironically are unaware that conflating streamer with model is bad 3) the types that want to have their boyfriend on stream and get free money from stinky nerds. All of these are bad people and they create bad times.
When vtubing is just an anime about cute girls playing videogames, it works. When it's a whore trying to hoover up money into her snatch, it's shit.
