> Vendors, cowed by Amazon’s overwhelming bargaining leverage and fearing punishment, comply—agreeing to raise prices on competitors’ websites (often with the awareness and cooperation of the competing retailer) or to remove products from competing websites altogether

Amazon has been openly doing this for years. They scrape other competitor websites, even though it’s against their terms of service, and if you sell for less elsewhere they find out and punish you. It’s blatantly anti competitive.
