But remember, UBER was playing in an unfair world. A world in which the existing Taxi companies had entrenched monopolies and yearly contracts with airports and city councils. And UBER does provide a valuable service to its users. I hate to go back to the days of having to call a yellow taxi cab to take me to the airport and then wonder if they would show up in time or not. //corrected a typo
How does that justify the alleged obstruction of justice?
Consider a case where the legal system was attempting to enforce property rights involving slavery and an individual obstructed the system. Many would consider this justified obstruction of justice because they are morally opposed to what the legal system is trying to do. (I'm not trying to say what Uber is doing is anything like the example I gave, I was only trying to give an extreme example where many readers would at least see how people would feel it justified the obstruction of justice.)
Legally, it doesn't at all.
