Reading this, I really wonder why the dev hasn't forseen this outcome. It was already obvious in March that OpenAI will censor all sorts of content. Building a sexually charged bussiness on the OpenAI API was always a dead end for those that have a feel for american prudish approach to sexuality. If you had asked me to do this sort of product 6 motnsh ago, I would have declined because it was (to me) rather obvious content filtering will kill you at some point.
Heck, there are a bunch of legitimate use cases that are being blocked by OpenAI. A blind friend of mine wanted to use Be My AI to have explicit photos of his girlfriend described. Guess what, no way. Consent was given, actually, she asked him to do this because she was also interested in the result. Everyone involved consented. But the sex filter from the USA decided that even though the technology is available, a blind man is not supposed to know how his own girlfriend looks naked... This is weird beyond description. Plain patronisation.
Another example regarding Be My AI: A blind woman I know was trying to have something described which she held in her hand to present it to the camera. A kind of selfie situation. Guess what? OpenAI declined to describe the thing in her hand, because the photo also contained parts of her (covered) breats. Imagine how hilarious this must feel? "Censoring just declared my own boobs to be off-limits for me." If you think about this long enough, its a form of discrimination. Because women will likely hit the filter more often then men when they are (accidentally) part of the picture they are trying to get described.
