The biggest problem I see today is that there are so many people who aren't even bothering to justify pirating, and instead insist that it is natural, good and just -- not just as a means to get access to content they otherwise wouldn't be able to, but for everything.
To draw my line in the sand, I have no problems with people pirating works they simply don't have any other access to. American shows that aren't broadcast overseas, for example; pirate away.
I don't personally do it, but I don't have any problems with those that do. Others, however, simply incur piracy as a matter of course. Looking for a new album to listen to? Limewire. Looking for a movie? Pirate Bay.
While I don't mind downvotes, that I repeatedly get voted down while suggesting that yes, even though copyright is wrong, it is the law, and people should either respect it or engage in civil disobedience (which is a public affair) instead of just casually pirating every piece of content they consume, it is telling of the more and more common mentality (or at least is becoming more common on HN.)
