Positively terrible... Kudos to this researcher. I liked Zoom when I used it a couple of times, but the reinstall “feature” is a huge violation of my trust. Software from the company behind it will not touch my system anymore. Too bad really, because properly working video chat is hard to find. The App Store model is not my favorite, but at times like these, a forced sandbox and inspection by a trusted third party start to look like the only way forward.
