A big problem, is that all the streamers are breaking the landscape into hundreds of different parts. It's pure profit-seeking, and I can't actually argue against the business sense.
But it makes being a consumer, a nightmare. Book DRM is similar. I like to use the same reader for all my books, but was forced to crack many of them, just so I could read all my books on the same app. I also brought pirated books, because they didn't sell the ones I wanted, in the US. I would have been thrilled to pay, but they didn't want my money.
Bundles tend to become corrupted. Cable bundles are pretty much worthless, to me. They all force you to have sports, and sports are what makes the bundles expensive. I couldn't care any less, about sports. I guess I'm in a minority.
I would love to see the ability to "build your own bundle," including temporary subscriptions to services that carry just one show I want to see (I remember subscribing to YouTube Premium, just for one show. I found it to be an awful app, and quickly unsubbed, once I'd watched the show). Maybe even the ability to select individual shows, from different publishers, and watch them all on the same app. AppleTV is getting closer to that, but still has a loooong way to go.
The tech is definitely already here. The issue is with the distributors.
