I found a zoom daemon running on my kid's MacBook a year after uninstalling it. Turns out uninstall didn't kill background processes, needed a reboot to flush it away.
i am more impressed that the MacBook had a year uptime. The kid never rebooted it?
I swear I remember this being called a feature, they left something around after uninstall so that if you clicked a Zoom link it could reinstall the client seamlessly. An ease-of-use thing for less technical people.
