Can we stop using and finding bugs in the close-source Zoom and direct that effort to finding bugs in the open source Jitsi (or any other open source solution) instead? Even though it's free and open source there will be bugs and usability issues that need to be solved. If we pool our effort right we can make open source solution into "just works" solutions, reducing the need for companies like Zoom.
