Employees and their families were directly threatened, and in context with the other emails (which included statements that said if you live near a theater, you shouldn't stay home, and specifically invoked 9/11) was a lot more than "we'll share your personal info".
Not you in particular, but if it wasn't so scary I'd find it funny that other folks keep dismissing any threat like it was ludicrous - because no foreign entity has ever had individuals in the US who were here to commit violent acts...
It's sooooo easy for folks sitting safe at home in front of their computers to say "no big deal, man up!" but it would be far, far different if they were employees at Sony and were getting these kinds of threats in their email. Folks talk all big because, Internet, but it's BS - and they know it. Particularly since, although I haven't seen it mentioned lately, when all this was going on independent security experts were sure that someone had to actually have been on-site to perpetrate this.
Again, this Monday-Morning Quarterbacking by some folks is simply machismo and completely and utterly BS - akin to folks who say they would suddenly become Superman and would have taken down the kid at the Dark Knight screening, when in truth they would have been laying on the floor frozen and piddling in their short pants.
