1. Despite the NSA, Facebook and Google + privacy incursions, prosecuting "leakers" and "whistle-blowers," and at the possible cost of being hypocritical, many Americans do indeed have a huge , almost limbic reaction to protecting first amendment rights. The pulling of any movie for any reason gets many of my fellow citizens really hot under the collar, reason be damned.
2. Sure, a private media company's IT system has been invaded and possibly destroyed. This is bad, but not fatal. I think what worries Americans is that if a country that cannot keep the lights on for its population, or even feed them, if this supposedly backward weird realm can invade and destroy a sophisticated company's IT system, what is to stop them from shifting their obviously effective hacking from Sony to, say, a power company?
