Jellyfin Project Leadership Changes

I never understood why they don’t support the subsonic protocol.
Also, there’s no native Jellyfin app for my phone.
In the end I changed to Navidrome and use it with a subsonic-compatible app.
Also, my server is still PHP-free and I’d like to keep it that way.

So to answer your question: OpenSubsonic is only for music, and Jellyfin does much more than music. Adopting OpenSubsonic would mean maintaining two APIs, which doesn’t make a lot of sense.
Meanwhile Navidrome is adding Jellyfin API compatibility to get access to more clients :P
