By the way, and this is half a MOD NOTE: Don't say whether or not you, yourself, engage in illegal software downloading/sharing. Remember Rule 6. I want to debate the pros and cons of DRM, and illegal software sharing is part of that discussion. Whether you think that downloading software should be free, or at least far cheaper than it is (the nonlinear movie editor Sony Vegas is 400 USD), don't say, implicitly or otherwise, if you download illegally. Ethical or not, it's still illegal.
More on topic, I also want to point out that I've heard of some studies that demonstrate companies actually grossly exaggerate the negative effects that software piracy have on their profit-margin. Makes sense; Game of Thrones has been listed as one of the most pirated shows right now, but HBO still has the budget to produce more.
The Free Software Foundation (with whom I agree on some issues and disagree on others) has also denounced the term "software piracy", because of its insensitivity. Their argument is that it basically equates a crime (regardless of the ethics, it's illegal and so a crime) that's on the same severity as petty theft, to the likes of Blackbeard, Henry Morgan, or Francis Drake; murderers as well as thieves. They're also the ones who regard DRM as standing for Digital Restrictions Management. They do believe in accurate terminology, and in these cases, I agree with them. (Not so much on the whole naming of Linux as a whole, whether Linux is fine or if it should always be GNU/Linux.)
They prefer the admittedly more cumbersome phrase of "illegal software sharing", and I generally agree that that would be a better term. (Much like how the hacker community hates how the term for themselves is commonly equated to computer criminals, when the term is supposed to refer to anyone who can take something apart, figure out how it works, put it back together, and make something new from it; they prefer to call criminal hackers one of two things: black-hat hackers, or the more derogatory crackers. ^_^)
