Its niches are nowhere near as strong as reddit though. The only reason I can’t ditch reddit is small hobby subs and stuff like that. Their alternatives on lemmy are just not good enough, because of a hideous combination of lack of users and fragmentation.
They’re probably talking about Samsung TVs, not their android phones/tablets. Installing jellyfin on those things can be a chore. My experience with LG was similar. The official build was out of date and riddled with issues that didn’t exist on other versions. It refused to play videos that worked well enough on other devices, transcode or no.
