How does Jitsi handle 500-person+ conference calls these days? This is the killer zoom feature - it looks like Jitsi can handle up to 500 now. https://jaas.8x8.vc/#/comparison . That's personally not enough for many remote companies. So if we're going to have to have Zoom on our machines anyway (to handle an all-company meeting), why not just use it for the rest?
Are 500-person conference calls actually productive? Surely the number of speakers in any such meeting will be a small percentage of listeners?
It's more of a large-scale broadcast situation. Think of large corporate town halls, town council meetings, etc.
