Who in their right mind would use Zoom as a service. My employees will never connect to another conference call with a third party that uses zoom again, ever.
I appreciate your sentiment but sometimes there’s immense pressure to use it because it’s what everyone else is using, and refusing would cause a meeting to be disrupted (or force you not to attend).
But sometimes legal has the trump card in terms of dictating company policy, and having confidential information laundered into the public domain via training on "customer content" seems like a very red line.
