Well, yes, some people are like that, but they aren't hackers. Technically, hackers do steal. Text is what they are taking, written words and knowledge. Not the latest edition of Adobe Photoshop or AOLPhun. Hacker's are not the people you see with these sights proclaiming they have passwords for pornographic sights and saying that they have all of the software that you could ever need.
Hackers are people against censorship.
They are the people you see wearing the blue ribbons. Hackers are trying to find knowledge. Knowledge is power. And that's why there's censorship. Because if knowledge is kept from you then you're just one more person in the unknowing masses.
