My opinion is that making the content available when the publisher definitely does not want it to be so at a certain time is immoral. However, I feel that once the genie has been let out of the bottle, that item has just become public domain, whether the laws say it is or not. Should an end user feel bad for accessing that public domain? For me, that's where things get cloudy.
If a person has the books on pre-order and then they get a sneak peak at it, I don't consider it as bad as when a person had no intention of buying the books and then gets them for free. If the latter person then goes on to use the material and still does not buy the material, then I think that a moral line has been crossed.
In this case I would like to think that most people who are downloading the books are just taking an unauthorized sneak peak, but are still planning to buy them.
At any rate, someone on another messageboard pointed me to a location where the books could be downloaded. This wasn't a torrent site, but an actual download site where one click gets you everything in its entirety. I forwarded the links to
WotC so they can try and get them taken down. The decision to honor copyright law was an easy one for me to make. I can wait another week and a half.
