RE: I suspect they will have the book
"Copyright infringement is wrong, we have fair use, but just blatantly taking the fruits of another person's endeavours is just wrong."
Are you sure about that? I mean, you've been taught to believe it just like some muslims have been taught to believe blowing themselves up amongst innocent civilians is right but that doesn't mean it is a fundamentally correct belief.
I'm not commenting either way on whether I think it's right or wrong, but your wording is the type of wording the RIAA/MPAA loves- "taking the fruits", well no, that's not true, you're "copying" them. While you've been taught to believe that the copyright system is correct and that copying a song someone else made is wrong, just stop and look at the bigger picture- how many meals do you cook that are from recipes that were created by someone else before you?
You see this is the fundamental battle here, historically it's been too hard to prevent someone copying the recipe for jacket potato, or fish and chips so it's always been seen as foolish to try and do so. Historically it was quite hard to copy movies, and music that was produced on physical media and so a business was built around the fact people couldn't copy it. But then it became possible to copy it and it's become easier and easier to do so. The music industry is trying to hold on to a philosophy that with the prevalence of ease of copying is about as possible as someone inventing a new combination of pizza topping with run of the mill products from the supermarket then banning anyone else from making it such that they can only buy it from him.
The fact is, music, movies and software are anomalies when it comes to protection by copyright law, they're anomalies that have been allowed to exist because the facility wasn't previously commonplace to allow easily breaching these rights. Recipes, house designs, flower arrangements as random examples off the top of my head amongst many other things all easily copied and hence realised that it's foolish to try and make it illegal to do so. On the other hand, something like car design is illegal to copy simply because it's too hard for the masses to copy such a thing. What we're seeing here is a business that was built on that premise entering an era where suddenly that premise has been whipped away. We're seeing the fallout of something moving from controlled distribution to easy distribution by the masses and those who previously held that control are lost and confused by the transition. It's going to happen, they have no choice in it, the cats out the bag, it's already too late. It's just sad that people like those running the TPB making this point in a rather subtle manner have to suffer in the process of moving towards the inevitable.
One final point is that this hasn't just been brewing recently, it's been brewing since people could copy casette tapes, it's just become ever more prominent and ever easier to do since then and the music/movie industry have become ever more desparate as their entire business model slips from under them. They have a choice of changing their business model and adapting or they have a choice of struggling until their very demise, so far, they're simply choosing the latter and losing even the battle for hearts and minds in the process.
