I see a lot of these comments have taken to a kind of Amazon-bashing and venting their own experiences, where the author actually... didn't?
I thought the author was incredibly fair/objective, and at least the way I read it, it wasn't so much that he had such a miserable experience or could only stomach 10 months of pain/abuse (in fact if you actually read to the end, he praises his manager, his teammates, etc.), and more so that it only took him 10 months to realize that the company culture and way-of-working was not aligned with his personal preferences. He does have legitimate complaints about parts of his experience, and makes some keen observations about the consequences and tradeoffs of Amazon choosing to adopt the culture that it does (though I also think he's wrong about a few things too), but overall it's less of a "Amazon == bad" piece and more of a "this is why it wasn't to my taste" reflection.
Frankly, I would congratulate the author, and think of this as a success-story. Paraphrasing his own words, he learned a lot, met some good people, found some good practices that he's going to carry forward with him... isn't that a successful outcome (minus the annoyance of another round of job hunting, but hey in this market, another job hop is probably just an opportunity to level up comp, rather than an existential threat that you might be unemployed and starve)? Obviously the team/org he was in is suffering major attribution problems, and that's obviously a bad thing, but that's not his problem either.
Note: in case it wasn't clear, I do work within Amazon, but these opinions are my own, not representing my employer, blah blah
