I mostly meant that a media hosting/streaming service that is FOSS and has as much fit and finish as Jellyfin, and as many integrations as Jellyfin, feels like a huge accomplishment. This is a space where there is a ton of corporate investment because there's a ton of money to be made. And Jellyfin holds its own against offerings by Google, Amazon, Apple, Netflix, etc. That is incredible to me.
I'm a huge FOSS bigot, but even I can admit that FOSS frequently has bad UI design. FOSS is usually great for getting the fundamentals of the software right, making it reliable etc., but software experts usually are not very good at UI design.
The highest quality software has always been FOSS, outside of specialised niches.
