Movies are expensive to make, and watching them on streaming gives almost no money back to the studio. The intention is that if you want to watch a movie, you should pay the $5-10 it costs to do so on any of a number of platforms. Then you get the great user experience of putting any movie you like into the search bar and pressing "play", and the studio gets appropriately compensated. Putting a movie on a streaming service is a way for studios to double dip, to get a smaller amount of money from people who don't care which movie exactly they watch. If you have a particular movie in mind to watch, or don't like the fare on whichever service you're subscribed to, you should be paying a la carte for movies instead. If you aren't, don't pretend it's some moral stand and not just you being a cheapskate.
