Netflix plays what their subscribers want to see
Then why do they have so many reality TV shows? Ugh.
No, but really, the set of inputs to what Netflix has is quite complicated. They love things with cheap per showing licenses, like off-the-air TV shows, unpopular movies, documentaries where the producers are more interested in pushing a message than making a profit, and a smattering of more popular "draw" shows/movies to bring in the popular audience.
And then there's the loss-leader shows trying to get people to start watching the series as it comes out, either on pay services or with commercials.
And then there's the various "taste profiles" of the people who are netflix subscribers, and what's both cheap and good within that frame.
There's some pitiable accountants in the company who's responsible for balancing all those factors, while making a profit.
Reducing all that to "giving the people what they want" is a little unpragmatic.
