Netflix spends a lot more on per developer, and has been working on the UI for longer: See, for instance, how a big percentage of manpower at Disney has been spent going from two completely different UIs between D+ and Hulu into a single one, so every feature didn't have to be made multiple times. Those kind of projects, with a quantity-over-quality approach to hiring, tend to take forever.

Netflix also has an advantage in cost management, also due to better engineers that are also better paid, and have been managing their system for far longer. The AWS bill for D+ is not the kind you get when you have good chances to be profitable. I bet a lot of engineering in the next year or two will be used just more efficient use of compute and storage. I bet many teams there are spending far more on servers than on people.

And if D+ could be doing better, and is still unprofitable, imagine the situation in other competitors that are even newer. The total cost of the infrastructure, without even counting the licensing or the marketing, might cost the more than people are paying.
