If you talk to someone who works/worked in publishing or the creative arts scenes (MFA programs, etc.), you'll see that KI is likely
specifically addressing that crowd - his industry.
I think a lot of the general populace is aware of the dynamics that he's talking about, but in publishing it's another world/level.
Interesting example that's the norm in the space: the story "I Sexually Identify as an Attack Helicopter" by Isabel Fall. Bear with me as I likely butcher the pronouns/terms etc, but my intent is earnest and well meaning here...
Isabel is a trans woman author. She/they weren't out when that story was published in a scifi mag. The story makes some pretty obvious references to sexual/gender identity, and the writing has very specific commentary and sometimes mockery.
Isabel, not known to be trans at the time, faced a torrent of online abuse for ~appropriating/joking about/exploring concepts about gender identity. The motivation was pretty clear: Isabel wasn't trans (as far as the public knew).
The story had passed some "sensitivity readings" too (yes, sensitivity readers are another interesting area to explore), but the online reception was still awful. There's also a difference between criticism vs. outright internet abuse. Isabel's experiences were pretty firmly in the latter.
The author took down the story, I believe came out or the news outed her/they, and the details go on (finger pointing, revisions of criticism about the story given light of the author's gender, etc.).
The point of all this is that's an insane dynamic to create in, and that's the tip of the iceberg really with what Publishing is going through. Young Adult fiction is apparently one of the ground zeros for this dynamic.
