I read that Lyft donated a million dollars to ACLU, so that may be a good alternative.
(Also the fact that uber does surge pricing in the first place… evil and horrible. Plus the whole company’s model is to be dirt cheap juuust long enough to rub out the competition–taxi services–and then to jack the prices up to taxi prices. Until then, they’re bleeding money, just hoping to wait it out until people have no other alternative.)
