It’s definitely not as lightweight, but as I rely on subtitles a lot I have to run most stuff through Kodi unfortunately. I find it to work quite well though with the Jellyfin add-on. I don’t know if it’s because the development of Jellyfin is mostly done in the US, who often dislike subtitles, but this has been an ongoing issue for years at this point.

I’d recommend running Jellyfin server but using Kodi as your frontend, best of both worlds, especially if you use subtitles as subtitles still work really poorly on Jellyfin

I’d wager he means something like the fediverse, reddit, various microblogging sites. There are plenty sharing experiences working for Google, Apple and what not.
