IMO, you've totally lost all proper perspective for the situation.
I don't think anyone here has lost perspective. We just think it's wrong that you are profiting from someone else work and didn't even ask if they minded.
If you can't understand our misgivings, then I don't know what else any of us can say. Except, that your cavalier attitude about the situation seems to have turned away many people who were willing to purchase the book.
