Hypothetically, let's say this writer is really talented. Few writers use hyphens for maximum effect. So few readers get to experience the hyphen-joy. When they do finally encounter it, they might be confused or annoyed. To some of us, that's sad, and aggravating. The technical glitch, at least at first glance, feels like the symptom of a larger lapse in longing for literacy and appreciation for poetry.
My harsh response notwithstanding, I'm all for experimentation in literature.
I'm just not at all sure this is a technical glitch. As far as I can tell from the excerpts mentioned, the author probably does actually misuse hyphens. I'm not very prescriptive when it comes to language, but there is a point where you have to consider it to be an error instead of a mutation.
Edit:
OK, the book is back up and it's on Kindle Unlimited so I grabbed it and skimmed the first few chapters. So far, not too bad on the hyphen front, just a couple of instances I caught (water-bed jumped out). It might get worse later, of course.
But unless it's messing with screen-readers as posited above, perhaps Amazon did blindly react on this one. I've certainly seen much worse.
That said, holy crap the writing is profane. I don't think I've seen this many fucks in one place since I stopped watching C-SPAN.
