Criminals winning cases on technicalities while still having committed the crime is not justice. Justice is getting punished for crimes actually committed. Justice is when innocent people are acquitted of crimes they did not commit.
Turning Dotcom into somekind of folk hero is ridiculous. He became very wealthy by facilitating theft. It isn't like he was donating the proceeds to build schools for girls in Afghanistan. If he broke a potentially unfair law as a statement and did it for something other than getting rich, maybe then we could consider him something other than what he is -- a self-serving criminal.
