These people don't go to fairs, it's true, but they do bulldoze the fairgrounds to build a data center. To build a semblance of consent, they need to host brainwashing events like "fairs" and so on where they can propagandize and threaten citizens. They can't hire a local artist to advertise it, because literally none of them will do it. AI comes in handy when you're absolute evil.
Local farmers market, now thats a dramatically different clientele than the county/state fair. Bread is like $9 a loaf there so you can imagine what sort of individual that selects for.
