I don't see piracy as a black and white issue, even though it can be damaging to a developer's income (or spur positive word of mouth and lead to more sales than it would have gotten otherwise).
In some cases, it's a matter of accessibility and pricing being unreasonable. Other people simply do not care and would rather get it for "free" if they are able to. The onus ultimately falls upon those that try to sell content to give people less of a reason to pirate something, as piracy is something that is impossible to prevent. Those that never intended to buy it anyway wouldn't have an effect on sales necessarily.
One reason I wouldn't bring myself to care is one, it is not my responsibility to care, and two, it would require some degree of cognitive dissonance given the amount of casual piracy that is normalized in society today (and to a significant degree in some countries). People still pirate movies, (e.g. cable) TV shows, pornography, manga/anime, music, and other types of content daily, many times without being cognizant of what they're doing. (Heck, several threads here would be rarely posted in were this not the case). Content and digital rights misappropriation on a minor level is almost akin to plagiarism in that we seldom worry about it outside of specific contexts.
Granted, the climate is and has been changing as content delivery models, too, are changing, allowing people to legally access that content through similar channels due to support through ad revenue and such. I'd see the distribution of pirated content as more problematic than the act of acquiring it.
