I’ve been meaning to set up a homeserver with plex recently but will defnitely go for jellyfin now that I read this thread.

The shutdown notice you link to only concerns the tedd.it instance not teddit as a project. Of course the other instances face the same issues though, so these alternate reddit fronts will probably still take a huge hit in user interest and development or even wind down since spinning up your own instance is to much hassle for a lot of people.
