Probably not an original idea but
C!s, not CC!s, if that even needs to be said for stuff like this
TW blood mention I guess oh and also violence and talks of insanity
So you know how right after the Red Festival, when everyone is hanging around Pogtopia and Tommy's mad at Techno for killing Tubbo, Wilbur keeps trying to make everyone get angry and fight "for content"?
Well if it's content, it's for us, the viewers and chat, but chat in-universe can be a lot of things. Only one creator is well-known for having a violent chat that makes him do things, and that's Techno. We call his chat the Voices.
So perhaps, we can assume that Wilbur has HIS OWN Voices, but they aren't bloodthirsty (or not as much,) they're just sadistic, and that is arguably a lot worse. Whether or not they contributed to his downfall into obsession and insanity is a different matter.
