Not necessarily true, as the success of streaming shows. The problem comes when the unbounded greed of the billionaires in charge leads them to inflate prices beyond their customers' ability and willingness to pay.
Streaming was cheaper than what existed before, and still is. Inflation-adjusted, movies and TV were insanely expensive back then, yet people willingly paid. And the movies were better. Who's greedy, companies wanting to offer nonessential entertainment for a price, or people who want it for free?
Nobody I ever talk to cancel Netflix because it’s too expensive. They cancel it because it runs out of content they care about. Including me. I’m not keeping a sub for that one week a year I find something I enjoy.
It's both. I canceled when they increased their pricing again (a few months ago), because there's no way I'll pay more when neither the service nor the catalog gets better. I would have kept my subscription if they hadn't increased the price, regardless of any changes to the catalog.
