It's certainly a good point-- It's not like competitors that also work together is a new concept. Except I'd say this is a bit different. We're not talking about Netflix relying on Amazon to produce a hardware component, we're talking about Amazon staffing and being responsible at the lowest level (24/7) for Netflix's service to operate (I'm assuming a bit here... perhaps Netflix can still function through an AWS outage). And I'd question if that's really something you want to put in the hands of a company which wants to steal away your customers.
