Yes, they have. It took the pirates four days to even begin getting parts up, and tomorrow's DDI update will quite likely put the crunch into the Compendium and the Character Builder before the full book is available. As it stands right now, the vast majority of people who preordered or who have a DDI subscription will have the book's info before pirates do.
Well, I guess that is a matter of opinion. If its about a race to get the preorders to customers before the Pirates get a PDF, then O.K. Contrasted to the number of people that learned as I did how easy it is to make our own PDF (for personal use), and spiral bind the book afterwards, I think they lose out. I doubt I will ever bother to purchase both a PDF and a book again; all the delay accomplished with me was slowing my purchase by a few days, waiting for someone I know to let me spend a few hours with it to read over & decide if I wanted it.
I think that there are a lot of people like me who will always want the physical books, for character design, casual reading, etc., but who use laptops exclusively for actual gaming, and so will alw3ays want electronic media too. It stings that WOTC has yanked PDF's without a replacement in place.
But as I read over this string, it seems that a number of us (like, me for instance) are being led by our feelings, and a lot of noses are out of joint. And it clearly goes straight to the top - it all began with WOTC's nose out of joint re

iracy.
[response to point 2, "tomorrow's DDI update" - yes, and a day or two later the new April patch will appear for the Cracked character builder, and those damn Pirates will be neck and neck with us again!]
