yeah, but intent matters, and someone purchasing an ebook is probably making a good faith attempt to obtain the media in a way that compensates the author - hence my elision in the passage i quoted, which seems to mean well, but is badly phrased. a downloader pirating the book is directly violating the author's rights wheras the purchaser is really also a victim along with the author - they are being deprived of money for something the seller has no legal right to provide. ianal and all that applies, of course!
