That honestly doesn’t sound like a bad mission, but it seems like there’s a couple other requirements they should impose on their mission and then there wouldn’t be any controversy.
They should require that their package works as well as the upstream, and, in the even that it doesn’t, they need to be very blatant and open that this is a downstream package, and support for it will only be provided by Fedora Flatpaks, and that you may have better results with the official packages.
The primary issues in this case is that it doesn’t work, and it’s not been clear to users who to ask for help.
It looks like as long as the host has a Plex pass, this doesn’t change much. It is a regression of service, which sucks, but there are viable alternatives for those unable or unwilling to pay. And honestly, jellyfin is the clear winner in that case and always has been.
Now, if they start to charge my friends and family for access to my media after I have already paid them for their lifetime subscription, then I’ll grab a pitchfork with the crowd.
Also, why not run both and be ready? The resources required are minimal if you’re running via docker, just some extra RAM and a negligible amount of compute for overhead on library maintenance tasks.
