It never ceases to amaze me how companies choose the worst software!
That's personally not enough for many remote companies. So if we're going to have to have Zoom on our machines anyway (to handle an all-company meeting), why not just use it for the rest?
It's more of a large-scale broadcast situation. Think of large corporate town halls, town council meetings, etc.
If something they said in the main presentation was missing important details that you need to do you work, why do you need to wait days/weeks for them to gather all the questions, find all the answers, and publish a video, when they could just answer it live in a few seconds?!
"At that scale there'll be no interactivity during the meeting anyway."
