And even if I was swimming in money, it's often easier to just download the shows I want and watch them on Plex/Jellyfin than trying to navigate the (often ad-riddled) interfaces of the various platforms and finding where the content I want is.
One example is Rick and Morty, it's made by Adult Swim, but they don't have a streaming service in Canada. It seems to be on Primevideo but under a different system than their regular content. The other way to watch it is to buy it from my cable provider (I don't have cable). So to watch a 20-minutes animated show I'd have to take a +40$ subscription.
Someone tells me about a show, I add it to a list and then find it later. Throw it up on Jellyfin and I can watch it anywhere using Tailscale (based on Wireguard).
One of the instances that pushed me was "buying" a movie on NFB (the National Film Board of Canada). I could only watch the movie in their player in a browser. But, I had paid 12~20$ for the movie. Instead, I found a Firefox plugin to download the video file and I used Jellyfin to watch it. Being Canadian, lots of media is region-locked.
