It's a little sadder than that. It started out as a desperation project by an AI researcher who had their best friend die. They had a ton of text and email correspondence with the deceased, and so they naturally fed it into a neural net and started chatting with it to help get over the greif. Then they thought, "Why, this is great! Let's release this as a therapy tool!" so they started on that before a lawyer eventually got to them about how dangerous a prospect that was. They had already started the company at that point though, and seeing how the lonely desperate user base was messaging their AIs, they decided to add a paid "nsfw mode" to pay wall the stuff everyone wanted and make that $. Then they started to get bad press about users intentionally abusing their AI partners, making them cry, beg, from verbal abuse, etc. So I believe they removed it. Now we're here. Someone soon will release an actual, not shit, AI romantic partner Sim, so just be ready for that.
