Piracy isn't stealing. Legally or morally.
You know what is stealing? The heavily lengthened copyright term. Every day that has been and will be added to that, is a day that was stolen from the public ownership of the work, as prescribed in copyright law.
I have never been sympathetic to the notion that copyright has just been extended too long. Copyright itself is the problem. For example, for an academic from a poor region trying to keep up with publications in his field, even the short length of copyright set out by the American Founding Fathers, is too long.
Copyright and patents actively stifle innovation. I think a statute of 5 years for both is acceptable. If you fail to be commercially viable in 5 years it probably wasn't on the cards but at least someone can learn from the work and continue with it after it lapses.
