I feel the same way about book piracy as I do about any other information piracy -- Take what you can get when you can get it, and if you consistently enjoy what you get from a particular source, do what you can to support them. I don't think information is valueless, but I do believe that it is heavily overpriced in a lot of cases. Given that, I don't think it's wrong to thoroughly investigate a book/game/album/etc before deciding whether to pony up the dough for it, nor do I have any problems with adjusting what financial support you'll give a source to amounts you feel more reasonable about. Beyond that, I think that development and refinement of tools used for piracy of information-based products such as those is important to keep those tools available, easy to get, and up to date for people that would send rather than receive data around some attempt at a roadblock -- mostly people that would report covered-up problems in regions with secretive controlling govts, but I'm sure other examples come to mind if one thinks about current and recent historic events for awhile.
As an aside, I don't know how the BGs feel about this, but for me, can we not call everything The Foo Fallacy (particularly those things that aren't even fallacies, or are poorly-defined if they are)? Stormwind and Oberoni were unnecessary, but useful for getting people's attention. The others are just part and parcel of the rampaging asshat behaviour over at Gleemax, and I'd really rather not see stuff like that become habit around here, this place is too good for it. Agree, disagree?
