I think it says something quite dark about our society as a whole that we have basically commoditised distress and are encouraging some people often themselves in dire circumstances to prey on others to the benefits of the middle men. I find these new pimps scarier than the old sort in that they pretend to have clean hands.
Anyway, a lot of people who have never used the site before think it's mostly what you said. It's not. The parasocial stuff is tiny unless you're doing specific kinks for people.
What I tell most people not familiar with the industry is that it's usually more like seeing someone in real life (NOT a porn star, celeb, etc, amateurs only) that you've got a crush on naked for only $10/mo. It has the amateur thing a lot of people love. Another reddit comment is always "Why pay when porn is free?" Have you never had a crush on someone? And amateur porn is probably the biggest "kink" I feel weird even calling it a kink, I'm practically on the "who doesnt like amateur porn??" end.
That's 90% of the customers. Lots of people who think a youtuber or instagram or whatever not professionally showing themselves off is just hot and want to see them naked.
I've never spoken to a single customer. I'm a straight man and most of mine are men and I have no interest or desperation for money to do para/kink stuff.
I really don't get why so many people think onlyfans is about messaging talent back and forth. It's kind of annoying to constantly read because it always comes from non-OF users who have this weird morality/ethics problem with sex work. It makes no sense if you know anything about porn. Most people jack off in silence and close their laptop and there aren't thousands of onlyfans models with media managers. Most are 18-25yo women who work corporate jobs or bartenders and have their own life to live. They treat it like youtube, upload content a few times a week and never look at messages.
Don't kink shame, stop with the "I don't know why anyone uses this instead of that, you're a loser if you pay for porn" thing. You like what you like, other people like what they like.
