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.
Giving all the data to zoom probably means also giving it to most US law enforcement agencies (should they request it), that would be a big no no for me.
