Thanks for sharing your thoughts Michael, Julian. Webinar is more appropriate for a larger audience since it allows finer control on who and when can share content [1] and it is less susceptible to Zoom bombers.
It is true that it might be a bit annoying to ask for permission to talk/share content but it is not uncommon for events with more than few (10) people. Hosts can add panelists (people who can share audio/video/screen) before and during the event with 1-2 clicks so I don't see any big advantage for switching to a regular meeting. Possibly, next time what we can do is add the people who are interested in sharing audio/video to the panel before the event but still at request basis. Finally, let me say that if somebody wants to be added as co-host at the meetup group [2] in order to organise an event I would be very happy to add him.
