It's probably not my place to be speaking for other people here, and I'm probably begging to get flamed...but I think the reason most people pirate is due to the fact that if it's there, and it's free, then why not? Sure, it's morally wrong, but that's never stopped anyone before. Cheating on taxes, speeding, changing lanes without a turn signal, going to the store and not reminding the cashier if they miss some item or not going back to a store if they give ya too much change.. none of it's moral but unless you're a saint, then you've probably ended up doing something morally wrong in your life. I pirate. I have a couple thousand worth of software on cd or my PC that I didn't purchase or at least register, and I really don't have some deep down sorrow for what I do at every LAN I go to.
I could be wrong, but the reason most people do what I do is cause they don't really care. It probably does effect some people, and I'm sure it can't help the industry, but, as someone stated earlier, people are hypocrites in general. I'm sure I could afford it all if I wanted to, and yes, the money I've spent on my PC and the upgrades I'm saving for now coulda been saved for software, but I had better things to do with that money, plain and simple. Look at it this way - if you were walking down the street and found $200, nobody around, would you look around, pick it up, and walk off, happy to have such great luck...or would you pick it up and go door to door, trying to find who it belonged to? It's not the best analogy, but you know what I mean. It's human nature. If it's there, and it's free, and you CAN do it...well then, a good 90% of the people out there would go for it. Not to say what the majority does means it's right, but it just proves the fact that while some people say they're morally straight and upstanding, they're most likely hypocrites too, to an extent.
Anyways, to the people against piracy, that is why I believe people who pirate do it. I'm not advocating or putting anything down...but answering the question.. "Why, when you can pay for it?"
Just my $.2
