I thought about replying to some comments but decided to make a top level comment instead. There are some valid points a few people have brought up that aren't the easiest things to fix. Some are, actually pretty easy to fix. Some are issues where Jellyfin forces you to do things a certain way, like file naming convention, which I think is extremely smart to do anyway.

But the one reply I keep seeing is "until Plex stops working, I see no reason to switch". With that, I mean, I guess we all agree you are going to get fucked by Plex at some point. They've been slowly cranking up the heat in the pot. I love my media library and I just couldn't stand waiting for the rolling boil. I've been using Adobe products since 1999. I recognize an abusive relationship when I see it. If you're happy where you're at, I mean, by all means. I'm not going to yuck your yum. Many of the issues are exactly the kinds of things the Jellyfin community is happy to help fix with you. I do wish you all the best, but I've never gotten locked into a great deal that didn't hurt when I needed to get out of it before.
