It's a pretty trivial CRUD app, if you want to be dismissive about the actual tech involved, but if you've read any of the discussion, you'd see that the tech largely isn't what's being discussed here. (And I'll bet the tech stack that powers FB messenger or Snapchat is endlessly fascinating, but you could similarly derisively call those CRUD apps.)

OF is fun to talk about because, well, it's porn. But looking past the empowerment of mostly young women (top earners make O($100,000/month)), OF is of particular interesting to the HN crowd because it exposes a lie: digital money is not the same as physical cash. Having a gatekeeper say what you're allowed to spend your money on, is antithical to freedom. Whiiiiiiiich leads to cryptocurrency, which many a reader here finds interesting.

The other theory that was previously being floated about was FOSTA-SESTA laws, which purports to be against sex trafficking, but ends up hurting the very group it says it's against, sex workers. Those laws are what closed down Craigslist personals and Backpages, for better or worse. (Which, according to sex workers, worse, since it has lead to sex workers being killed.) But see this is also of interest to HN readers because those bad laws mean a founder-CEO could face jail time if the police believes their MVP app/website promotes sex work in a primary way.
