I would care about them too. I wouldn't expect you or anyone else not to. But according to the studies I've taken, it's up in the air about those people. There are people that are transient between being a pirate and a buyer, both back and forth. But they don't make up a major part of your buying base. This isn't a justification at all for their behaviour, but I mentioned earlier about a 'guilt complex'. When people have pirated books, they're more likely to recommend a good book they pirated as opposed to a good book they purchased. So in general conversation, word-of-mouth of your pirated book is more likely to come up as a recommendation, and maybe a new buyer. It happens on a large enough scale that it does result in a portion of purchases that can be less or more than the number of "buyer to pirate" purchases (but not zero, so it's not a whole loss). So ideally, their loss in buying results in your gain in purchases, or at least some of that loss back. Which is why I can't see piracy as the big boogeyman that it's made out to be. It's not a scary thing that's going to ruin your career as a writer, especially if you write well. Of course it'd be better without it, but hey, it's here to stay. I guess all I'm doing is 'soothing the savage beast' here, I'm not saying this stuff to say piracy is awesome lol! I'm saying it to reassure you that piracy isn't a big scary monster that spends it's every waking moment trying to destroy any chance you have.
