Jeff Bezos is a remarkable person, though his anti-competitive actions would probably be criminal in many countries. IANAL but if anyone built a case against Amazon in the WTO based on their disgusting international price dumping to destroy weaker competitors, they might win. The book has a ton of evidence.
Anyway, the book shows many positive things about Amazon. Since the book was published, the Amazon stock just keeps going up and it more than doubled just this year.
The book does discuss all the seeds for the current growth (Prime and AWS) so it still feels up to date.
