Famous composer Jason Robert Brown has a great discussion on the theft of intellectual property over at his blog. Maybe I'm too old, but I do not understand the girls arguments. For me, it is obvious that someone suffers when I steal. I have been raised to respect someone else's property (and there is no difference if this is a thing you can touch or a thought/idea/song/story). Aren't kids like her aware that they are actually stealing? Do they think writing a song or a story or a novel is easy-peasy and we, the creators (authors, songwriters etc), do it just for fun?
Writing a short story can take me as long as a week. Writing a novel will take the better part of a year, if I work 4-8 hrs a day. I do not think it is justified for ANYONE BUT ME to distribute anything I worked so hard for for free. If I decide to give it away, it is my choice. If someone else steals it and passes it on, it is not my choice - and this is not considering the form of compensation for the work of a human being that societies all over the world agreed upon (talking about money here).
If young people do not understand that what they are doing is illegal and hurts the artist they (admittedly) admire, they might wake up in a world where artists just can't afford to create any more because they are too busy to make ends meet.
Think about it, and please spread awareness about piracy if you can.
P.S.: In Germany, you will get into jail for four years if you are caught. I think that although it might not help much, I might make some kids reconsider.
