Thanks for raising this concern. I moved your post here so we can talk about it some more.
Zoom is a pretty amazing, feature rich tool for running webinars which is why we use it. It really helps ensure a smooth experience for everyone. You can see how that works if you view the recordings from past events tagged webinar.
Do you have experience participating in webinars hosted with jitsi, or hosting them yourself? How does that work out for you? Are there other tools you’ve used that you would be comfortable with?
