Why the hell does Zoom require root access to begin with? I used to work on a competitor and while it would have made some things easier we never found anything we wanted to do that was impossible without root permissions.
The only annoyance is having to manually extract it out of the downloaded archive when I want to update it. But IIRC, this takes two commands, not including the commands to swap the new app bundle with the old.
The downloaded archive is compressed with xar, and I believe that one should be extracted into an empty directory because otherwise it will spray files everywhere. Then the app bundle is in a gzipped cpio file...I think it's at Contents/Payload.
It does some unusual stuff that it probably doesn't actually need to be doing.
They have taken the market by storm, because most people care about the former, not the latter
