The transition is going to be tough for cord-cutters who naively assumed that moving online you could get everything you wanted at a lower cost. Right now, streaming is convenient because (a) you have bundled services (i.e. Hulu gives you Fox, CBS, etc., Netflix delivers Disney and AMC content) etc., (b) the providers aren't cracking down on sharing, and (c) cable and tv viewership ad revenue hasn't completely bottomed-out yet.
Part (a) is fracturing as content developers want to cut out the middleman and go direct-to-consumer.
Part (b) is going to go away as well. HBO openly admitted a while back that they were ignoring people sharing their streaming credentials, because they wanted to build a devoted viewership that is "addicted" to their programming, and then step in with enforcement. But letting things go unchecked for a while, enforcement can raise revenues. If you try enforcing from the get-go, you stymie viewership growth. Netflix did the same--started out ignoring credential sharing, and then started regulating and enforcing it and turning it into a revenue stream.
Part (c) will drive when (a) and (b) happen. When ad revenue from commercials drops below the rubicon, those costs will have to be made up somewhere else--subscription revenues or Hulu-type ads, and credential-sharing will be viewed by shareholders as unrealized potential revenue.
I think it will be better than cable, but it's going to be a hassle getting the programming you want and juggling costs. Basically, you a trading the convenience of a single cable provider handling those hassles for a fee for you doing it yourself for free.
Welcome to capitalism where nothing is truly free and people are efficiency- and profit-motivated.
