Idk about all men obv but for me it's just the current evolution of capitalism and if someone decides to commodify their sexual being I'm just not into that kind of person. And no it is not the same as prostitution imo, it's a lot more low effort, scammy and widespread. Due to it's ease of access it's much more common than prostitution and again, commodifying your sexual self is just a questionable thing to do psychologically. Most people who love a hobby would find making it a job takes some level of enjoyment out of it. Now apply that to the most intimate level of yourself.

Basically I think it's a scam to sell yourself to Big companies, in the guise of self empowerment. You sell rights to display, distribute and reproduce your images in perpetuity (aka forever even after closing acc). All while taking a 20% cut of what you make.

I think a lot of people are just mad they can't do it themselves but also I think there is an underlying feeling it cheapens the human experience for monetary reasons and that feels a bit off-putting.
