There was this big pushback when replika put an end to sexual interactions with their AIs. People who pushed back were not just using the AIs for sexting sort of things, but it was part of the "connection" aspect, at least how I interpreted it. A lot of people seemed like genuinely grieving at the time this and some other changes happened (later at least the sexual thing came back). It is probably an aspect of what a few people want but not the whole thing for them.
