I can't stand the thought of using Zoom after all the seemingly endless issues on security and privacy (and now this new issue with not paying a bug bounty). For what might probably be a millionth time, what are the best alternatives (preferably free or easily self-hostable or priced low) for occasional calls of the following types: 1. Video calls with some people (say about 10 people max.). The free Jitsi Meet seems good for this. 2. Webinar platform where there are clear distinctions between a presenter and participants, and the presenter chooses what's visible at any point in time (video feed from camera or some file/presentation/screen sharing) and has control over recording the session. 3. Same as #2 but with two presenters on camera (different physical locations) switching back and forth (either as the main view or with the active presenter on the main view and the other in a smaller corner window).
