Ok, this is pretty off-topic, but is this still true? I get that you can't have 10K people all actively participate in the meeting at the same time, but doesn't Zoom have a feature where you can broadcast to thousands and thousands?
Doesn't X/Twitter have a feature like this? (Although, to be fair, the last time I heard about that it was part of a headline like "DeSantis announcement of Presidential run on X/Twitter delayed for hours as X/Twitter's tech stack collapses under 200K viewers")
But still - nowadays it seems like it should be possible to have 10K employees all tune in at the same time and then call it a meeting, yes?
