How is desiring technical depth in a technical post "gatekeeping"?

The ananlogies are horribly pained. It is an excess of empathy that ruins technical writing that could otherwise be quite rich with information. This attitude of writers having to do all the work needs to end; let the reader do some of it

edit- its reductivist to think that only SWEs would understand this stuff. Have you forgotten about the legions of IT professionals and computer nerds that many SWEs came from? The rich history of hacking, much of which this post laments? Or is that kind of nerditry simply unfashionable nowadays?
