I can see where you might argue that telling 900 ppl simultaneously that they're fired, over zoom, does make sense, but there is an element of true cowardliness about how this fellow went about it. He's not vulnerable to any real human backlash in this context, whereas a manager or CEO saying the same kind of shit in a one on one meeting would.
