The first time I encountered VTubing, I thought the point was just to hide your face, for various reasons. Being sensitive about your looks, not wanting to attract stalkers, whatever. But there's apparently a lot more to it; I was surprised.
If I were to make YouTube videos of the camera-to-face variety, I would cloak my face and voice both to avoid stalkers and to avoid deepfakes of each.
But against the flood of videos even before all the AI-generated content churned out by people who don't care about quality, I think I will instead just not make any.
That's what many western VTubers don't get, they see it as an "avatar" for themselves which is not what VTubing is. It's supposed to be a completely different persona with no connection to your real identity. It completely dilluted (and I would say even ruined) VTubing in the west.
There's a lot of indie vtubers who do it for that reason. It's just that the biggest ones are corporate.
