I have to agree with this, as a matter of morality. Legally, there is an obvious difference, as we all know. As a matter of ethics, though...I'm trying to think through the harms that could be caused to the rightsholders by fans reading the books early:
halplm wrote: I am fully anti-piracy, but I don't like the way they handle these releases, and while I am going at midnight, and will buy the book assuming they have a copy for me... I fail to see the difference in me reading it now, vs being able to check it out from the library on Saturday... other than an arbitrary date that is not that important to me.
Some people know what's happened by the official release, so the hype is lessened. The big questions will have been answered for some people - is Snape good or evil? Does Harry live or die? Who are the two main characters who die? (Incidentally, I don't yet know the answers to these questions, and I'm not going to look at what hal has posted until I read the answers for myself.) It seems to me that some intangible loss of "hype" only practically harms the publisher if it leads to fewer sales. I see two ways this could happen. First, fans read through the book online before (or theoretically after) the release. Either because they are disappointed with the ending, whatever it might be, or because they do not want to read the book more than once, they don't buy the book.
For most fans, this is inconceivable. Due to some combination of morality and loyalty to the author, most WANT to show support for the book as soon as it goes on sale. So the potentially lost sales, it seems to me, are sales to less-serious fans who only want to know how the book ends and only need to hear it once.
Even for those people, I gotta say...I doubt these particular leaked images are going to do it. The most wieldly form I'm aware of is a nearly 400 page PDF containing each scanned image back to back - hardly an ideal, or comfortable book-reading experience (before the PDFs appeared, apparently people were opening the work image by image, which sounds even more daunting). It would be hard to find more amateur looking images. In each scan, a berber carpet with red and green flecks resides in the background (I gotta say, one of my first reactions - thinking about the legal crucifixion at Scholastic's hands that the seminal infringer likely faces, if caught - was, "How stupid do you have to be to photograph the book on such a distinctive carpet?" Ten bucks says that if Scholastic gets the information based on DMCA subpoenas, they go over to the kid's home (seriously, I don't think this person could have hit their thirties) and find him/her lying on that selfsame Berber carpet smoking weed.) More eerie are the disembodied hand(s) residing at the bottom of each scan. (Again, I had a moment of "Really? You go to the trouble to take at least 400 photographs and put yourself at IMMENSE legal risk if caught...and you can't bother to use a higher-tech means of holding the book open when you photograph it than your HAND?") Lastly, some scans are far lower quality than others; the reader has to turn the monitor sideways (or, according to newspapers, a higher-tech fix is to sharpen each image individually in Photobucket), in order to read some of the words approaching the binding on certain pages. Hardly an ideal e-book. It's difficult to imagine that anyone other than a pretty hardcore fan would even want to make the effort to read the book in such a trying fashion.
And those fans? They'll buy the book this weekend. Maybe some of them will wait until Saturday morning instead of being there Friday at midnight, since they don't have to stay up all night reading. But their numbers will be reflected in the first day/week sales.
