I have many lights, gadgets, and appliances in my home. But I only have one power meter. Which I flip a switch or push a button, different things can happen, but the meter just counts the watts, and at the end of the month, I pay one bill. That's convenience. Everything I own takes 120V 60Hz AC power, and I pay one monthly bill to run all of it.
The convenience problem with the fragmented streaming services is that everyone wants to run their own wire to my house and put their own meter on it. They need to agree to use the same wire, adhere to a common protocol, and allow resellers to act as their meter reader and bill collector.
That didn't work with cable companies because of locally-granted monopolies that prevented the signal reseller from experiencing competitive pressures, but if everyone can choose between DirecTV Now, YouTube TV, Roku, Sling, Netflix, or even RQ Hacker's Streaming TV Reselling Service, then the consumer is still in control. Partially.
Cable could force you to get 100 channels when you only wanted 5 of them. There was no one else around to sell a package with fewer channels, or even to go full a la carte. But even then, content owners could still strongarm content distributors by selling their channels to the cable companies and satellite distributors as one package. Now it's just the same thing all over again, with the consumer cutting out the middleman, and finding out that it was the supplier that was screwing us from the source all along.
The copyright holders name their price, and those who want to watch have to pay it.
What we really need is for someone to undercut Disney by ripping off their format. Bowdlerize the folktales and fables by taking out all the viciousness and cruelty, create a few trademarkable characters out of them, write a few catchy original pop songs, and stitch together into 90 minutes of family-friendly video entertainment. Throw public domain in one end, turn the crank, and get intellectual property sausages out the other. It would probably only take a few billion dollars to make an impact.
Or... maybe take a hammer to the copyright law that Disney bought, and blow the dust off the anti-trust laws. Maybe draft a new law such that no content owner can sell a bundled package of works unless they already distribute each component individually, and it must be priced such that the price of the bundle must be within a certain percentage, plus a constant, of the sum of its components, purchased/licensed individually. The ultimate source of the fragmentation problem is the copyright laws. It will never go away until they are reformed. So I'm not surprised that the fragmentation is apparently promoting piracy.
