I just finished reading the book and it was a good read. The people that are discussed in it have responded and while they are well placed to comment on its accuracy, there are two sides to every story. It’ll be interesting to see if the author responds to these accusations:
Over the course of the author’s reporting, Amazon facilitated meetings for him with more than half a dozen senior Amazon executives, during which he had every opportunity to inquire about or fact-check claims made by former employees. He chose not to. I met in person with him on at least three occasions and exchanged dozens of emails where he only checked a few specific quotes. He had every opportunity to thoroughly fact check and bring a more balanced viewpoint to his narrative, but he was very secretive about the book and simply chose not to.
