There are a couple reasons. First, Amazon has hundreds of businesses and almost 700,000 employees globally now. Every business has different culture and managers. You are not going to find a consistent good/bad/indifferent experience here, because it's highly varied. I can guarantee you a seasonal worker in a fulfillment center has a vastly different day to day experience from a software development engineer in Seattle.
The second reason is that people tend to write about negative experiences more often. You see this all the time in Internet forums where people complain about products they bought. There could be millions of happy customers of a product, but the few thousand that got a defective one or had a bad experience with customer support will loudly and vocally scream about it on the Internet, which at first glance, seeing hundreds or thousands of reports of a terrible product, might seem bad, but the millions of people who used the product and had no problems with it are not going to write about it.
Disclaimer: I've worked at Amazon for a few years now, and I've had 3 decent managers and one terrible one. The good thing about Amazon is that it is relatively frictionless to switch teams.
