This is the point of sandboxing apps in the Mac App Store, and (to my understanding) providing simple and complete uninstallation. Mac users that care about issues like this (and I'm not saying they shouldn't) can avoid them by choosing to only install apps from the App Store.

Revoking signing keys on the Mac is pretty extreme considering that Zoom is creator of the software — and that is what the key is meant to prove / enforce. I think that sets a very bad precedent.

The fact that Zoom is distributed outside of the App Store should at least raise eyebrows for Mac users. At this point, I tend to ask what specific functionality is required by an app, such that it wouldn't be allowed in the Mac App Store — especially for free client software (there can be perfectly valid reasons for this, such as previous versions of BBEdit).
