I'm not sure what you mean. The documentary seemed fairly middle-of-the-road and interviewed both fans as well as models. It's pretty clear that parasocial relationships aren't healthy (whether it's with a game show host or an Onlyfans model), so I would definitely push back against "almost all the customers know it’s a fantasy."
You have no idea whether the interviews are with a realistic sample of the customer base. All it takes is focusing on a couple whackos to make the entire customer base look similar.
And if you made that documentary, who would you focus on? The normals, or the outliers? If you want the most entertaining product that will make you the most money, you’ll choose the outliers.
Not saying this is the case here, but as a documentary nerd, this is absolutely not true. There are plenty of cinéma vérité documentaries out there.
Don’t base your world view on anecdotes from a carefully edited documentary. In reality almost all the customers know it’s a fantasy, so what’s wrong with fantasies?
