Wow, I didn't expect this many people to be against piracy. If you think downloading games/software is morally wrong (and thus you don't do so), then I assume you're not downloading music either (or a huge hypocrite). Aren't all those songs on youtube copyrighted too? Okay, most music doesn't get deleted by youtube but is that by choice of the artist? Or does he simply know that he can't prevent his music from appearing on youtube? By that reasoning I'd find listening to copyrighted music on youtube equally morally wrong. I just can't immagine there's this many people not downloading music or watching music videos on youtube.
Aside from that the risk factor plays a huge role in our criminal tendencies, hell if there's enough cash involved and the risk is low enough practically everyone would steal. I believe because there is no risk in piracy it doesn't matter if it's legal or not, what matters is if it's morally okay. It's probably selfish to download illegaly because:
One, you screw over the company/creator of the wares.
Two, you screw over everyone that does pay for their wares, if there was no illegal downloading prices would drop.
Still I download illegally, I guess I'm just selfish like that. Why should I care about some huge company losing money if it's never coming back at me? Nobody genuinly cares about what happens to someone they don't know if it will never affect them, most like to think they do because that makes them feel good inside. I don't give a rat's ass and I come out on top, where others might spend hundreds of dollars on software, I can get myself a nice PC.
It pays to be selfish.
P.S. The "I only download what I wouldn't buy argument" is shit. First off you wouldn't know if you would buy it because the fact that it's available for free shifts your priorities, besides it's a way to easy excuse. I wonder how many people who go by that argument actually practise it. If you download illegally you're amoral and selfish in the eyes of the community, simple as that.
