I disagree. I don't think that different streaming services are replacements of each other. It is inaccurate to think of them as mere "video services" (if they were even Youtube would a substitute which it clearly isn't). Their value is in the exclusive rights they have secured for different content. If a streaming service has an exclusive deal with any one of your favorite shows, you are pretty much going to have to buy it.

Speaking for myself, I have bought the subscription of at least four video services in India.
