I personally don't give a rat's tail how the copywrite owners make their money. There is no doubt in my mind that this book should be available on the internet freely so that as many people as possible can read it. It is the responsibility of those in control (the Dykstras?) to make it happen.
Many people who read the PDF will want to buy the book (as i did). It can only help the cause and it will help line their pockets with the money that made this whole thing an issue in the first place. We'll no doubt see their true intentions depending on what they do in the near future... If they provide an avenue for reading the book freely or through a donation arrangement then I can see that this isn't just another money grab.
