Bingo. People can be so tribal about this shit. If you value privacy and hate subscriptions, jellyfin is you homie. It isn't as hard to set up as some would have you believe (i'm a normie and have used it for years).
If you don't give a fuck about privacy and don't mind paying some creep to make it easy for you to access your own files, then Plex is fine. This is the camp some people are in, and it's just as legitimate as mine. Life is about gray areas and compromise.
