@Forever Sunrise pretty much mirrored my reasons for my distaste of VShojo. I don't find excessive toilet humor particularly funny, and when basically your entire personality and selling point is "I'm a cute anime avatar saying fuck dick" I have zero interest in you. The fact that a lot of them are typical cunty western women, or troons, doesn't help my opinion. They are absolutely only doing VTubing because they saw it as easy money and a hype train to hitch a ride on.
Many, if not all, of the Hololive girls will likely stick with it when this initial hype wave finally comes to rest, especially since most were doing it before it exploded in popularity. I imagine most of the VShojo girls will likely jump ship as soon as they see numbers dip and they have another trend to leech onto for easy cash.
