Well, it is, assuming that you live in one of the countries such as Switzerland or The Netherlands that either already legalized it, or at least decriminalized it.
For the rest of you, the question is this: If piracy (that is, individual, non-commercial sharing of otherwise copyrighted data) would be legal in your country, would that change your feelings in any way about whether or not the people using it are thiefs/assholes/self-entitled freeloaders respectively?
(Vote "other" if you feel that it was always a morally ambigious or acceptable or neutral act to begin with).
I'm asking this because in te usual "morality of piracy" threads, we tend to hit a wall when we get to the point of wheter it is the letter of the law that makes something right or wrong, or it's something that's inherently there. So this time, let's focus on just that.
