I'm very hesitant about zoom. I use it for conference calling at my job and download the app when I had to listen in to a meeting I was off site for. The meeting ended I exited the call and thought nothing of it, then an hour or two later I got an access notification that zoom had opened my camera, while I was under the impression it had quit. Their technique of downloading an executable every time you open a meeting from the web is also strange and somewhat uncomfortable. I do agree that it works brilliantly but I have my concerns about privacy and safety regarding it.
