Amazon is not infringing intellectual property rights like Samsung, but created platform/market places for everyone!
Apple, Nike, Disney surviving with IP (Moat) and extremely cheap cost ! Unless Amazon copies the IP and start producing, it is hard for Amazon to beat these companies.
You remember those days Apple went down from $750/share to $400 or below !
Few years before I quoted, if Apple is not matching big screen iphone, it was supposed to be doomed forever. Initially, Tim Cook denied to make, but finally released iphone 6 and 6 plus. If they have maintained like iphone 5, customer obsession is not there.
Apple is not customer obsession, but about product and quality.
