>>503676932d waifus are a bastion for men who want to feel like they have control over their life. The last thing they want to see is their waifus interacting with other men. Vtubers naturally satisfy a man's desire for the 2d waifu that can talk and interact with them, but as a business model it's important for vtubers to grow and interact with as many people as possible for networking. This will eventually cause them to reply to a literal mutt or chud and treat them like a person that exists.. or even worse... stream with them. This is probably the worst thing that can happen in the mind of someone who wants to continue to have a 2dwaifu that talks to them and only them.. As such, people here are obsessed with NTR. It's like the worst thing that could ever happen to them. It's a blatant display of no self-confidence/delusions from parasocial relationships.. also a desire for control that will never exist.
