If fic writers want to put details into their fic that you don't enjoy or *gasp* want to write to their own predilections, they certainly can. You're certainly not paying them to write, much less write something that you specifically will find hot. Until there's money on the table, they aren't writing for or to a particular audience, much less you. They're writing for personal satisfaction... which is where those personal details and predilections come in.

(And why most prompts on kink memes don't get fills... because your kink certainly isn't going to be something that every writer wants to write. And they've got no obligation to write to you or for your enjoyment.)
