Why the hell are prime ministers using Zoom in the course of their civic duty? Are they discussing national secrets over Zoom? Without end-to-end encryption?! That's some form of criminal negligence and/or mishandling of classified information in every jurisdiction I know. If not, it's little more than a nuisance and a reminder that Zoom should not be relied on for important communications.
