My experience with Amazon was extremely positive. The author of this article seems very junior / immature, and honestly feels like he's got some mental health issues going on. Airing this much dirty laundry is not likely to get you what you want, and is likely going to make it hard for him to get hired by the next company. Always talk to your boss 1:1, face to face. Never give shitty feedback over an online system. If you can't work out your issues, or you don't get along well with your manager, best to just move on and look for a new job.
