This article has a balanced, IMHO, business oriented view on piracy:
it ends with:
"I believe in paying money for products that earn it. I do not believe in a pricing and distribution model that still thinks it’s 1998. And I really don’t believe in censoring the internet so that studio and label executives can add a few more millions onto their already enormous money pile.
Treat your customers with respect , and they’ll do the same to you. And that is how you fight piracy."
