Not sure where I said or suggested the people breaking the copyright were doing a service. I think people want a legal means to have the book provide a service.
I think most folks agree that, and I do as well, that the decisions on what to do with the copyright are not ours, and are in the holders hands.
This is just business for me. Make money, cool, but don't blame everyone else for bad business decisions. Just ask HMV or go to your local, video store, they all made bad business decisions and they are not around. If you restrict content on anything, it gets out. (Netflix, geo-restrictions, etc...). This is so classic old school thinking. I think people are only wanting to help promote the book, and quite possibly see the current holder as the detriment to that do to the fact it has availability issues.
No doubt, piracy has impacted the potential sale of this book, but due to its limited target audience its also advertised it better than most publishers would. Hammonds work on this would say its helped, while Libowitz & Zentners work would say it hurt, so the messaging on piracy and book publishing is mixed.
