People have many reasons to be upset at surge pricing. For example, how transparently do they use surge pricing? How can we be certain it's due to demand and not arbitrarily adding it? Why is it fair that if I'm out at New Years at 12-1am, or Halloween at the same time, that I should pay 6-7-10x the normal price, which could turn a $10-$20 ride into a multiple hundred dollar ride? Is it fair because an algorithm put it in place, and just because it may be "fair", does that make it right, e.g. the terrorist attacks in Australia when demand when through the roof and surge pricing went up to 9x? Are we sure that every part of that surge price is going to the driver, which it's supposed to? Of course there are valid reasons for surge pricing, one of which is to keep supply with demand and ensure that the driver feels justly compensated for going somewhere they might not want to, but to say people aren't justified in their being upset at it because "it's 2016" is disrespecting the reality of the arguments against it.
