The supposed root exploit found in Zoom also requires physical, logged-in access to the machine, at which point a Zoom exploit is the least of your problems [2].
Zoom is a solid piece of software, and the developers are responsive and seem to care. I'm disappointed to see it getting dumped on during the past few days. A cynic might even suspect a co-ordinated campaign by Cisco, considering Zoom was started by frustrated ex-Cisco employees and has had runaway growth during the viral crisis, while the same cannot be said for Cisco's competitor product WebEx.
