That's a recipe for an unhappy life IMHO. If I stopped using every service/product/business that did things I didn't approve of I'd be compiling my own linux distro (kill me) and probably growing all my food (of course where are you going to morally get some of the seeds you need?).

This kind of black/white thinking is harmful. Plex "just works" for the family I share it with, I have zero interest in being 24/7 tech support so I don't use things like Jellyfin. If this UI/UX improves enough then I might consider it but everyone I've shared my Plex with has been able to use it without peppering me with 100 questions. I seriously doubt the same would be true for Jellyfin.
