Pirating millions of dollars worth of books would land people in jail. Government went after Aaron Scwartz for "pirating" scientific journals.
I think the Aaron Schwartz case is incredibly vexing because he was obviously acting out of a sense of altruism without personal self-interest. I don't think he deserved the book getting thrown at him like that. But the whole copyright system, which people seem to think is simultaneously good and bad, kinda rests on not allowing those kinds of violations
