@Turkeyjerkey I also feel patronized by transparency; it's why in-your-face ecchi series make me roll my eyes when I'm reading even if the story is actually well-written otherwise.
Breaking it down more precisely, this kind of transparency stems from a shared understanding: the message is "we all know what you're here for, you've read something like this a million times, let's dispense with the pretense/setup and get to the good stuff." If you aren't a member of the group that's reading for that reason, and
especially if you disdain reading for that reason, yeah, you're going to feel patronized and insulted—the author is acting like they know you and know that you're a "shallow" idiot.
The phenomenon itself isn't bad, though; to people who read a lot of the same thing, skipping or speeding through bits that are basically the same as everything else they've read in the genre is actually preferred. (Just look at how quickly isekai and otomesekai zip through their early setting/premise-establishing parts.)
