Just a disclaimer, while I don't want to take a position on what is being said in this article (apart from the statement that its worth sharing), I do want to say that the tone is ... a bit unforgiving. I understand the author is a bit bitter because of the legal troubles mentioned at the top of the article, but I don't think it color's their opinion, just their language.

Many other reviews were just as critical.

Scott Aaronson wrote good professional critique where he just politely debunked the main points of the book. https://arxiv.org/abs/quant-ph/0206089
