I've heard this. He's very tough, even ruthless, in business. But, speaking only a customer, Amazon has always been quite fair to me. That being said, I do wish Bezos were more intelligent when it came to his political views.
Among his various heinous acts, he regularly dupes businesses into using one of hos services (AWS, Amazon.com, Amazon Fulfillment, etc.)
When anyone becomes successful, he notices, copies their entire business model, cuts prices and puts them out of business.
Everyone is just fodder for his avarice.
Evil SOB.
