It really isn’t trying to be interesting. Some people are very much service oriented, and honestly this is kind of shallow in perspective. Just like everything in life I’m sure some people just say it to be lazy. But others are legitimately more interested in giving their role-play partner what he/she/they want. I would encourage for the future that rather then writing blanket statements or “blowing a gasket”, maybe actually discern whether they are in fact just being lazy or their kink is to serve and pleasure their partner so actually stating their likes would ruin the whole point. They’re roleplaying to have a lice person they can submit to, and not just an empty wall. Please consider this before just diving in and accusing a whole group.
