This is a highly editorialized title. The title from the blog is simply "The Criminal Charges Against Aaron Swartz".
In fact the words "Fair And Reasonable" don't even appear on the page.
Before anyone replies to the editorialized headline, his argument (including the second part cited in the comments here) is that the charges were fair according to the law but constituted a minor crime in a way the law fails to discern, and this issue also happens to be his pet peeve. Which is probably true, but (also understandably for a legal scholar) doesn't touch one point: this was a political action and statement that tried to challenge the nature of this law, in the same way current shadow libraries also are.
