Uber CEO Travis Kalanick likes to talk about the unfair ways that taxi incumbents "protect their monopoly" against his popular product. But the bigger Uber gets, the more aggressive its own protectionist tactics become. CNN says new data from Lyft, a smaller rival, shows 117 Uber employees cancelled 5,560 rides with Lyft drivers around the country since last October.

Lyft has already been declared illegal in New York City. The city's taxi commission is threatening to impound driver's vehicles, saying the e-hailing startup hasn't complied with "safety requirements and other licensing criteria."
