The meeting itself
Google Meet
The evidence proves scale and nothing else: 100/150/500/1000 participants published per plan, 24-hour meetings, in-domain live streaming on Enterprise, a hardware add-on and noise cancellation. Not one word on screen sharing, breakout rooms, host moderation, or behaviour on a bad connection — capacity without documented controls doesn't clear the 5 anchor.

Instant meetings with a published limit of 150 video conference participants on the paid tier are what the captured pages show of the call itself. I found no public information on screen sharing, breakout rooms, host moderation such as mute-all, or how the call behaves on a constrained connection — I have to score the silence.
