That's what I was trying to hit on with 'one of us.' That we (the HN crowd) care mostly because he's part of the 'techno elite' so to speak. Less so because he's white/middle-class. It just happens that the 'techno elite' is (seemingly) disproportionately white (not sure about middle-class). It also doesn't hurt that we see him as a bit of a martyr because he got a prison sentence that we don't feel fit the crime (and therefore feel that he's drawn the ire of 'the man' so to speak).
