I agree with you, but I'd like to remind us of something. Netflix doesn't use AWS for their primary thing: streaming videos. So their AWS workload is probably just not that demanding. What runs on AWS is just a bunch of scripts for selecting which videos to stream. Since the costs of hosting these scripts are negligible compared to the cost of streaming videos, Netflix just doesn't care about the fact that they are overpaying. If something is responsible for 0.1% of your costs, the fact that you're paying 2 to 10 times more for it is easy to ignore. That's the reason why they still use AWS. Their needs are not particularly elastic, in my opinion. Yes, people probably access Netflix more often in the evenings and weekends, but that is true of just about every entertainment website or blog, and it doesn't make AWS cost-effective.
