A lot of what this administration will do is going to be illegal and nonsensical and dumb, but they will do so much of it that it will be impossible to effectively push back against it all. If you hear something that you care about, pick that and keep up with it. Don’t get overwhelmed by the torrent of stuff happening over the next four years.
This is especially true in the current media environment, where there’s so much noise that it’s really difficult to break in and sort through what’s true and what’s false and what’s missing context and what’s misleading and what’s technically true but there are other factors that change how it plays out in reality, etc.
It takes a lot of energy to keep up with it all, so pick something you care about and pay attention to developments about that. Maybe that’s trans rights, immigrant rights, democratic institutions, economics, geopolitics, military industrial complex, whatever. You won’t be able to effectively care about it all, so pick one and focus on that.
I had a few metadata issues with Jellyfin until I changed the primary metadata source to be the same as what Radarr/Sonarr use so they all the file names match up and I’ve had no issues since.
I also don’t have a notable issues with subtitles in Jellyfin, but maybe your requirements have more friction. Have you tried the (iirc included by default) Jellyfin plugin to automatically download subtitles for your stuff? Or the *arr program that handles subtitles (I forget its name)?
