As an exchange, if you keep some reserves in USDT and you think it might collapse soon, you might have an interest in dumping your positions before it completely loses value. Maybe exchanges would benefit from responding to such a situation collectively as you suggest, but I think it's likelier that they will just protect their own interests as individual entities.
