I bought a lifetime plex pass once and have no issues since. HW encoding works out of the box, the scanners do their job and I can use their apps on every platform. I had to disable the Plex offered free movies once, the horror. Don’t act like Plex is some Google level shit of annoyance or ‘enshittification’.
Jellyfin on the other hand has atrocious UI that basically screams the absence of any sort of UI designer into your face, the HW encoding is a mess to set up and the apps are a jungle of different 3rd party apps…
What streaming services is plex pushing? They offer integration for other services you subscribed to like Netflix or Disney and they also offer free, ad based services that you can permanently hide with one button. And the UI? Jellyfin is so convoluted, especially the settings.
