I can feel for both camps.

Some of my published work is pirated heavily. That's not my main income source, so I just shrug and let it go. If anything, I'm probably happy that people are reading my work. Especially if it's people that can't afford it, I'm glad they enjoy my work -- those books got pretty high reader ratings, and it seems to me many readers are actually reading the pirated version.

But I do have friends that depend on this income source, and fighting piracy has become a part of their day job. It's not a fun thing to do, they'd rather spend time working on their next story, but they still have to do this everyday. I feel for them.
