Exactly - that's why it felt like such a money grab. They raked it in for a few months, and then just let it go, free, on the web. How would you feel if you'd paid $20 for a PDF that was then let loose for free? $20 for a nice paperback might be ok, but a PDF?
(FYI, I didn't buy it, but it just didn't strike me as the most upstanding way of doing business)
