That is like saying that a kid who reaches through the fence to steal an apple from a huge corporate apple orchard isn't doing anything morally wrong, but the kid who picks one from one of the trees in the neighbor lady's garden is a dirty pedophile-burglar.
It is just based on unfounded stereotypes about how corporations are evil, while individuals are always good.
And it avoids just WHY piracy is controversial. The issue is not whether or not some owners deserves to get ripped off, but whether or not piracy is really causing meaningful harm to anyone at all.
Yes, World of Goo had 90% piracy rate. World of Goo was also a ridiculously hyped indie hit, that made millions of dollars of profit, where that piracy was either the CAUSE of it's success, by spreading the word of mouth, or an after-effect, where some people who didn't particularly care about it just got fed up with hearing about it everywhere, decided to check it out. (Crysis, Skyrim, Modern Warfare, etc, also have unnaturally high pracy ratio).
These kind of people are simply non-consumers. But even if you would assume that each of these are lost sales, just the fact that it could be bought for one cent, would make it exactly THE SAME as the above analogy with a kid and the apple. Or maybe not, an apple is probably a lot more expensive than that.
And no, I'm not "humanizing" pirates even by comparing them to kids. In fact, many of these pirates ARE kids, who simply don't have any paypal account to pay even one cent for the game, or adults who are just as ignorant about the Internet and ddeveloper revenues and copyright as a kid. They are a niche at the periphery of the industry. Treating them like a dangerous force that is trying to destroy us, is like demonizing that apple-stealing kid as an immoral person whose ways will destroy the apple industry.
