In the past (pre-Uber), if you made this amount of money by engaging in large-scale, coordinated law breaking, you were called a gangster and got a big old nice RICO charge.
Don't be confused or blinded by the valuation. That is a byproduct of breaking the rules. The rules were not broken because they were unfair - that's a meme - you don't get to pass arbitrary judgement of which laws you do and do not respect (in theory). As a business, if you do not like the legal environment (rules) of a certain location, the logical (and respectable) choice is to not operate in that region/location.
My view is 10x more harsh on companies breaking the law in a coordinated manner than compared to an individual person.
I'd say that's firmly on the "breaking the law" side of things.
I think most people consider onerous regulations to construct a barrier against entry aimed at any new market entrants[1] to be a different sort of law breaking than normal law breaking (more... morally and ethically acceptable). IMO Uber has flagrantly ignored a number of regulations regarding driver background checks that have allowed it to become less than safe to ride in, especially for single women, there have been a plethora of stories about women being stalked by uber drivers - even within the water-cooler talk at my office.
So technically they've broken a bunch of laws - and ethically they've acted in bad faith.
1. Please note, I think what regulations would be in this group varies extremely across HN, with the more freebretarian folks placing all regulations here, while others may consider labour regulations or environmental regulations to provide real value - and I really don't want to get into this discussion, I just think we can all mentally place a line _somewhere_
