I’ve no problem with paying for good services

Exactly. It used to be that netflix was all you needed to get most quality content, and it was a fair deal for customers: you pay a reasonable monthly amount, and you and your family gets convenient access to most streamable movies and TV series.

Now that quality content is spread out and locked out over half a dozen other streaming services, and subscribing to them all is not just a hassle but also incredibly bad value compared to the original offer.

In a healthy competitive environment, you would expect companies to counter reduced value by increasing customer value in other ways or by reducing prices, but instead we got price hikes, lots of low quality filler content, crack downs on password sharing, advertising, various unpopular UI changes and other service reductions decreasing value even further.

To solve this, I think the content producers and streaming services should be split up, because right now they're not really competitors in a true sence but small monopolies who each clutch the keys to their own little franchises. It should be noted for example that music streaming works a lot better: there are various competitors that each hold a viable content library on their own, so you don't need more than one music streaming service. IMO that's because Spotify, Tidal, YT Music, etc. are merely distributors and not the actual producers.
