Bezos cannot guarantee that employees may have access 3rdparty sales data. Can any big retail like Walmart, Costco, Safeway, etc. can guarantee that no employee ever looked at 3rdparty sales data ? If Walmart sees a cheap item flying off the shelves, and thinks that it can make a cheap copy of it, then Walmart would do it. Isn't how store brand work ? and they often use a white label producer anyway (i.e. same factory, different packaging/label). Walmart, Costco, etc. they know precisely what products you buy and how often. They can push you next time to buy their own version of it, by sending you a discount for for it, or simply rearrange the shelves in store. I understand that sellers with little to no competitive advantage, are very vulnerable to such practices. But this is hardly new with Amazon. They could avoid selling through those channels (that is why you find some products only through producer website, or direct sales). Amazon has 35% of the e-commerce market in US, or 6% of retail market in US (Walmart has 9% of retail market in US). Amazon does not do as well in the rest of the world. The 35% of the e-commerce market is in US. And even that 35% includes being an agent for 3rdparty sellers. https://www.ben-evans.com/benedictevans/2019/12/amazons-market-share19 https://www.ben-evans.com/benedictevans/2019/12/amazons-mark...
