On one hand, it's obvious that bullying the partner of a famous journalist is going to get negative media attention.
On the other hand, maybe that's exactly what they want. Maybe they know these laws aren't going anywhere anytime soon, and that sort of media attention ensures that generations will know what happens when they start asking the wrong questions. "Hey kids, just look at what will happen to your family if you start questioning the laws we make to protect you."
Would Greenwald have done a better service if he hadn't told the world what happened to his partner? I don't know--but maybe.
