[nmglug] Is Zoom an open-source app?

Hi NMGLUG folks, My business colleagues want to do video conference calls with me on zoom, from https://zoom.us/ I'm wondering if this is a program which has been reviewed by the Linux community, and if it has been approved as safe to use on Debian. I welcome your responses. LeRoy -- I am the Love of God, no matter what. LeRoy Diener 213-LEROYIZ 213-537-6949 www.leroydiener.com/
