While an argument could be made that JSTOR didn't want people downloading so many so quickly they could have solved that other ways - nothing here was breaking the law. It was technically legal.
An argument could be made that Aaron planned to publicly release them to everyone on the internet for free (I didn't get to meet him personally, but from what I know about him I think this is likely). That was never part of the crimes he was charged for and frankly I'm not sure if it was even alleged. JSTOR understood this, dropped charges and backed out.
He was then charged with 13 felonies:
Wire Fraud - 2 counts
Computer Fraud - 5 counts
Unlawfully Obtaining Information from a Protected Computer - 5 counts
Recklessly Damaging a Protected Computer - 1 count
Aaron was someone who probably would have been acquitted ($1.5 million dollars in legal costs later), who's actions weren't illegal that was bullied with multiple decades in prison and driven to suicide because he was trying to do the right thing.When asked about the government's actions in pursuing him, Carmen Ortiz defended her (and the government's) actions as "appropriate".
Is that Justice?
Copyright law was originally intended as an incentive for people to create, a deal with the government for a limited time monopoly in order to generate content for the public's benefit. The original spirit of the law has been lost - along with our republic. [1]
