My own thoughts on piracy are best paraphrased from a [now deceased] publisher of Science Fiction books. Jim Baen, of Baen books, he use to have discussions on a forum for his publishing website. He started selling his books in electronic format before any other publisher that I know of. His theory on selling his E-Books was to never encrypt them. This resulted in his books being out there for download on sites pretty much the day they went on sale. So this naturally led to many discussions on the topic.
He always said (paraphrasing from many posts here) he'd rather have stuff unencrypted so it made it easier to steal. Some people that will steal his stuff would never have been his customers anyway. So there is no business loss there. For the people who do buy his books he'd rather not treat them like criminals and encrypt everything. Automatically assuming your paying customers will steal it if you don't encrypt is really bad for trust and business.
And then there's a third category. People who are honest, but just can't afford it right now due to hard times. And there were many people like this he said. These people he was always especially happy they stole his books. Because those are the ones who, when they get back on their feet, are his future customers.
Think about it. The books they could get the easiest were his, and they liked them well enough they'd steal them and maybe even discover more authors they liked. When they did have money and started actually buying again who do you think they'd spend it on? The books that were encrypted and they never read, or the author they pirated eight of his series and the 9th is just coming out when they happen to have money to spare again?
So it was all very simple to him. One, you have people who would have never been paying customers, no loss there. Two, you have people who already pay, no loss there. And three, you have people who will potentially pay in the future. It's a no-brainer situation.
Pretty much summed up the whole thing for me right there. I'm okay with people pirating stuff.
The people downloading movies from PirateBay, does anyone honestly think those people would have ever in their lives bought those movies anyway? Ooh, here's a piece of shit movie in French starring no one I've ever heard of. Well NOW I don't have to spend $30 on that import! The world doesn't work that way.
As a side note. There was also several other authors who put sales records of their books up for public display. They showed their pirated books actually made them more money than they were making prior. They could track when older books were put out in electronic edition, sales of their new books increased. Pirating actually helped increase their sales.
Author Eric Flint did many articles on the subject relating to them putting books on their own website for free to anyone and the increase in sales that followed.

#6 is especially interesting into the actual financials of piracy.
