I hope Zoom gets their act together because their competitors, with way more time and resources, suck a lot more. I don't think it's because of the difference in security--maybe it's because competitors were focusing on Enterprise or because it wasn't their core business?
I think each of those companies that have banned it make sense, even if that means the average person should continue using it. Zoombombing elementary school children because of a misconfiguration (or just because of the media reports) isn't a great idea and the security concerns warrant the rest. I still don't see much of an issue for other business and most personal use.
