I'd love to understand that comparison. Amazon is a monopoly, and bullies the entire country. I don't know how anyone who learns more about Amazon in terms of their business practices and how they threat their employees would be pro Bezos on anything. You don't need to look hard to find horror stories on both the micro and macro with Amazon.
Microsoft and Windows has been long considered a monopoly and has been the most influential player in OS/Software for decades. It O/S has influenced other O/S, software development, application development and driven software compatibility decisions and hardware sales for most of the industry. I have literally heard everything thrown at Amazon at companies like MS before.
IMO, there is a good and bad that comes out of companies like these. For example, the small guy can build a store front which was nearly impossible before Amazon came along. It's all allowed individual sellers to flourish and allowed consumers to save a ton of money. They have pumped millions into communities and charities.
That's not to say there is not a dark and damaging side to companies that get this big. You mentioned some. My point is there is a ton of positive that comes from these companies too. It doesn't excuse the bad and Amazon should evolve. It's not so black and white.
At the end of the day, as a Sports fan, he made his money legally and I would love if he owned the Suns.
