Uber drivers are getting shafted; Uber can arbitrarily cut their pay, and they have to work 15 hours a day. Some are trying to unionize.

Uber requires running nonfree software, too; if you value your freedom, you won't consider Uber an option.

We should not accept the whitewash label of "sharing economy" for companies like Uber. A more accurate term is "piecework subcontractor economy".
