It being Israeli is definitely a big part of why this story is so huge. Why do you think it's making huge headlines then - what's your theory? The fact that 8 American diplomats got their phones hacked?
Follow the industry long enough and you'll know how Hacking Team (Italy), Finfisher (Germany), Gamma International (UK), smaller and larger firms have rightfully attracted their fair share of condemnation. Journalists pile on when a story gains momentum, this round was started by the published list of targets and Citizen Lab. We can't call this anti-semitism yet.
Defending it just because it's Israeli would be as unjustifiable as attacking it just because it's Israeli.
