Woosh. Try reading what is actually written rather than making up your own inaccurate imagined conversation.
The original comment was "A law is a law. Period". It wasn't "a just law is a law", or "a law applied to a company", or "a law applied to Uber". My point was to refute that statement, and had nothing to do with Uber's actions and my own opinion of them (which is generally negative).
In short, please try and read to the end of the sentence this time: What Uber does is often illegal, and often 'wrong', but the illegality in and of itself isn't the problem.
