The New York Times wrote of the case: “A respected Harvard researcher who also is an Internet folk hero has been arrested in Boston on charges related to computer hacking, which are based on allegations that he downloaded articles that he was entitled to get free.”
It doesn't even look like a copyright case, which can bring dire criminal sanctions if bad enough. It looks like allegations of abuse of JSTOR's facilities violating the spirit if not the letter of its user agreement; I don't even know if it bogged down their internet or their server adversely impacting other users. It looks very close to a no harm no foul situation from here. The world's gone insane.
