On some conferencing platforms, such as WebEx and GoToMeeting, meeting attendees who arrive before the meeting's host can not be put in conference until the arrival of the nominal host and can not continue to speak after the early departure of the nominal host (some, like WebEx, allow it but limit it to 5 minutes).
If, for example, a scheduled meeting of peers takes place and the nominal host does not arrive, even if everyone does it and some are prepared and qualified to lead the meeting, the meeting can not take place, at least on this platform with the published meeting ID.
These companies advertise their offers as alternatives or similar to face-to-face meetings. At face-to-face meetings, some people arrive early in the conference room (or filled in, in the outer hallway) and all attendees present are free to communicate with each other before and regardless of the arrival or departure of the student. Nominal host.
Host condition does not seem to be imposed by a fundamental limitation of technology; it seems that companies have had to do everything possible to strictly enforce the requirements for the nominal presence of the host.
Teleconferencing platforms could allow participants to join and leave a meeting upon their arrival and departure, regardless of the presence of the nominal host. (They could also limit this to a reasonable time around the scheduled time of the meeting).
These nominal host presence conditions appear to be set by default (if they are optional) by an intentional interface design choice. Why? What is the UX reasoning behind this decision? Who benefits and how?
