might be good to add "for video conferencing", this actually might make sense as the horrible teams app can be closed outside of video calls and they still use slack for everything else. slacks video conferencing is seriously lacking in bad network conditions so slack even recommends using zoom there and zoom is very expensive at githubs scale. if they forced this on employees for team chat that would probably be reason to suspect the beginning of the end. i would certainly consider quitting over using teams for chat.
