Re: Anyone heard of ...
Yep, spent a lot of time about 6 or 7 years ago evaluating it as an option for schools to begin using for remote learning.
It just had some interface issues, and the biggest dealbreaker for us was that the audio recording module was separate to the screencapture one, so stuff that was being drawn or talked about on the whiteboard was out of sync with the presenters speech. This may have been fixed by now...not sure.
I have G suite and just Google Meet...I'm consistently gobsmacked by how many of my customers on G Suite business ask me about zoom and have no clue they have a perfectly capable solution already in place. One thing meet does that MS Teams and Zoom can't is it allows both the presenter and the viewer to share their screens simultaneously, which really helps with troubleshooting and collab.
I think there is this misconception that all users must have a G suite account to use it...jus not true, anyone who receives the invite link can join...and it just opens in a web browser...no stupid OS based client needed. I can't speak to if there are privacy issues in Google Meet, I haven't checked.
Another one for self hosters is nextcloud, they have a video conferencing module. Very simple to use and join a meeting - of course depends on you provisioning enough bandwidth for your users.
