Well, part of it is being on Hacker News, which will definitely skew towards "self-host everything!", and on top of that Jellyfin is genuinely free and open-source while the more popular alternative (Plex) isn't, so probably more popular here again, and not necessarily reflective of the popularity amongst self-hosters in general! I definitely wouldn't expect it to be high on the list of priorities, but I do appreciate that it's under consideration at the very least.
