The policy of data caps certainly reduces all data usage, but it's a nuclear bomb to solve an anthill: they should just do a decent job of QoSing their traffic. Say "peak hours" speed is, I dunno, 15mb/s or something, and then offpeak is full speed. People can do their game/os/whatever updates off peak then, and as long as everyone isn't streaming netflix and downloading iOS updates while you're on a zoom call, you should be fine.
