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.
May it's something that is blocked or just not so popular in first world countries, but most of my Russian acquaintances use these services almost exclusively.
