Of course they aren't saying that, it would be political suicide to say it. But given the stubborn resistance to even using the credit card readers forced on them by utility commissions, do people really think that cabbies are aching to have apps between them and their customers that would thwart their ability to skip inconvenient fares or grab an easier ride on their way to a call? Uber's end-run around regulation is only possible because cabbies use regulation to make consumers' lives worse.
It's kind of crazy to me the degree to which the left is becoming a movement built around kneejerk status quo bias, based on nothing but a distaste for the idea that someone might be making money off of making consumers' lives better.
