Well that’s kind of baked-in to social media. If you’d otherwise talk to lots of different people in person, read much etc and now come to the internet and choose any of the mentioned platforms… That’d be bad. You’re now in a smaller filter bubble. If you’re already in some echo chamber and for example switch from mastodon to bluesky… that’s a minor change. The situation is a bit different if you change from a nazi platform to a regular one. It’s still not good. But better.
I enabled the DLNA server in Jellyfin. And that works okay with my LG webOS TV. But it’s down to the quirks of the TV which also likes to enable subtitles and the default audio track.
