Morally, it is a question of if the legal system is delivering justice or not. Obstructing the legal system when it fails to provide justice is not obstructing justice in a number of moral or ethical views. 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.
