Exactly my point. They are only trying to make money for themselves, and if exploiting a disaster make them more money, they will do that. Yet here we have people (like the OP) trying to claim that they are 'ensuring there are enough drivers'. Bullshit.
In crises, you get rationing no matter what. If you don't regulate prices you'll get rationing thru price. If you do regulate prices, you'll get rationing thru scarcity. Putting limits on Uber means you deny some billionaire fat cat some money, but you also deny the people who really need a ride and are willing to pay for it the ability to get one. I'd rather have the latter system where I can get what I need and am willing to pay for, because I can always decide I don't need it that bad, but I can't conjure a car out of the air when prices are cheap but cars aren't available.
