I don't know maybe its my values. When I do things that could have an effect on someone else I put myself in there shoes and ask myself if I would want that done to me... So if I was a music artist, or a movie director, or something of that nature, I would hate knowing that millions of people are downloading my music/movies for free, which is also known as stealing.
Remember how LiveWire got banned? Because he used Zelarons theme in his own website and Chruser got mad because it was his hard work being stolen? Well its the same exact thing.
Also I work for the government.
edit, just so you know I have a huge collection of movies games anime and music and I bought every one.
