Do you have an independent source of information that contradicts your position? Or is it all just guesstimating or what you feel should be right? Do you merely have an anecdote to tell us?
Do we have actual sales number? Do we have a peer reviewed study on piracy or sales? Do we have technical details on the processes used to track sales, download numbers or piracy? Do we have contradicting data to anything of what WotC says?
Why yes, as a matter of fact. http://www.ifo.de/pls/guestci/downl...orking Papers January 2004/cesifo1_wp1122.pdf
The money quote in the conclusions is "We have analyzed the RIAA’s claim that music downloads are causing a substantial decrease in CD sales. Our cross-section regression confirms their fear: we find that music downloading could have caused a 10% reduction in CD sales worldwide in 2001."
(Here come the ifs in the hypothesis) If pdfs are similar to mp3s in the patterns of acquisition then the 10:1 download ratio actually results in a 1:11 reduction in sales.
