That's because this notion of "bad guys" and "good guys" doesn't work in real life. It works in police and military situations where you take action against a declared enemy, but it's not a good tool for reasoning in a civilian setting. What you get there are not only different shades of bad, but also entirely different kinds of bad.

To point, there is really no question that Dotcom is generally not a good guy. He is a shady business man at best. It just happens that many people consider his brand of evil to be absolutely dwarfed by the motives and tactics of his government adversaries.
