Apart from that FBI warning of Zoombombing, I don't know a single non-tech person that's actually aware of all these security concerns, including China privacy.
Yeah, I've been seeing this all over. For example my sister in law hosted her wedding over Zoom this past weekend. Approx. 0% of the people who attended couldn't have cared less about encryption or security concerns. They just wanted the easiest way to join in on a video feed with their friends and family. It's even become a verb now: "zooming in" e.g. "Please zoom in to our meeting". That's the mark of something that's going to stick. Once searching on the web became "googling" in the general population it became impossible to unseat Google. I think the same will hold true for Zoom.
