YUUUP.
First off: Most Piracy is done on artistic mediums; Movies, Music, Video Games. For me art is something that should be openly shared for the health of our culture. Plus I've never met a real artist who would rather not make art if they're not making money, artists are driven by a desire to create and share that creation, money only becomes a factor in this equation for greedy pseudo-artists, who might as well be con artists.
Secondly: Being a lower-middle-class-American, born with the boot heel of the rich on my throat thanks to Reaganomics I feel fully justified even just outright stealing from most major corporations due to one simple fact: They've been stealing from my friends and family members as well as myself for decades through bullshit tax cuts and any price inflation they can get away with.
Let me put it this way: So long as I live in a country where Corporations are given the same rights as people, without having to pay the same taxes or obey the laws, I will continue to fuck them over every chance they get.
Because that's what I do to people who make it their JOB to fuck me over.
All of that said, if I were to pirating something created by an artist I would find another way to give them my money directly. I've spent more than enough on the game market over my lifetime to not really feel very bad about trying out games (Most of which I do end up buying as my Steam library shows), and as of late I've been investing in Kickstarters, which is way more direct than buying EA's copy of a Bioware re-release or whatever. With music I spend the majority of my money lately on shows and festivals and the occasional shirt, which gives the musicians way more money than buying their cds ever would.
And fuck the film industry, I'm not giving them back shit until they stop sucking. >_>
