It's the regurgitation of an insular community's bizarre beliefs, up to and including sexual fixations, back to that community for unquestioning consumption... a vore-ouboros, if you will.

Edit to add: I think there's a concentrated lump of illustrative lesswrong in this passage:

Also especially popular these days is a ZKP of your own tastes: as almost everyone has developed kinks that put a relatively normal goblin kink to shame, people have become more anxious about unaccepting people finding out. So now you can confirm that you and your girlfriend have a CPU-cuck fetish in common without her ever finding out that you and your grandma both enjoy spankings—amazing!

Yes, "ZKP" is dropped in without elaboration or definition. But more fundamentally... why, though? This reads like someone has thought too long and yet also too superficially about kink. Why has "almost everyone" developed these bizarre new tastes? What taboos are they transgressing, what vulnerabilities are they exposing, what strictures of life are they seeking to escape? What's the itch?! And yet look at the fetishes that are specifically named: "spankings" (literally, not figuratively older than Aristotle) and a thinly science-fictionalized kind of swinging. This isn't a new frontier in depravity; it's a bachelorette party for normies. The whole thing feels like a product of a mind that's strongly confined to a narrow understanding. It unhesitatingly accepts the importance of "freaky" sex and goes out of its way to bring that into the story, but it has nothing to say about the subject it has locked upon.
