I hear this line of thinking a lot but I don't really buy it.
You could just as easily say it's amazing that Amazon allows a competitor like Netflix to run on it's platform. The reality is that relationship is more complex than that.
Netflix is going to exist regardless of whether Amazon lets them run on AWS.
Amazon letting them run on AWS is brilliant as they get a piece of Netflix's pie. So even if Netflix beats Amazon Prime, Amazon gets to dip into their pot via revenues from AWS. It's a great hedging of bets.
They're totally separate businesses. The people that treat Netflix like their customer aren't the same people making strategic decisions about Amazon Prime. Amazon is a ridiculously large company.
