Unless it’s a purely social brouhaha, 8 people is the absolute maximum tolerable number of participants for a meeting on Zoom. Six is better.
The only people that enjoy over-stuffed video meetings are director-level and above, because it lets them can gaze upon their reports like Jesus on the Mount. For hoi polloi, large meetings offer nothing: There’s low interaction, there’s obnoxious cross-talk, introverts are absent, extroverts dominate with low-calorie contributions, no actual work is being done, and with more people it’s easier for participants to hide in distraction. So why bother?
If the content of a meeting is meant to convey information to a general audience, a shared document is a better choice.
In other words, that meeting should have been an email.
