That's not entirely true though. Netflix had to be prepared to provide that service. Meaning they needed to be able to have the capacity to serve the videos if necessary. Some times just having that capacity has a cost in and of itself. Not to mention they still are producing content whether you watch it or not, and by subscribing you are paying for that content to be created. It's more extreme in other scenarios, like say hospital emergency rooms. But it still applies to services like Netflix imho.
