Can't speak for obs and raspbian, but jitsi definitely is more of a hobby project than a stable reliable product. I have dealt with it firsthand for years and its a complete mess and unstable with poor quality and reliability and zero support. It tries to do one thing, and does it horribly. Users HATED it. Ending up costing our company millions in wasted dev time and hosting fees. Probably the biggest project failure ive personally witnessed. This is not something you want to use to offer some service to users. There are better and cheaper products out there.(it costs more to host crappy jitsi than it does to just pay for zoom licences).
