Arr! Today be talk like a pirate day, so let’s talk about the fuzzy boundary between piracy, popularization, and preservation.
I’m all for creators being able to profit off their work, and not about to defend people who pirate content just to get out of paying retail price. And some media is a lot harder to justify pirating than others; I can’t think of an acceptable reason to pirate e-books, for example. (It’s also a bad idea because you’re more likely to get malware than the correct book.)
