The meeting itself
Google Meet
Published capacity I can actually plan against — 100/150/500/1000 participants per plan, 24-hour meetings, in-domain streaming at Enterprise, and a hardware add-on for rooms. But the evidence is silent on moderation controls, waiting rooms, breakouts, behaviour on a bad connection, and any diagnostics an admin can read after a call fails — and I judge a product by its worst meeting, not the capacity slide.

Published capacity exists — video conferences up to 150 participants, with chat groups up to 2,000 under MLS — but that is where the published meeting story ends. We found no public information on screen sharing, breakout rooms, host moderation controls, behaviour on a constrained connection, or diagnostics an administrator can read after a bad call. When the board meeting stutters I have nothing published to hold the vendor to.
