The overarching question is at what point does a private citizen/activist become culpable. Developing technologies and social networks (old school kind, not facebook) which are explicitly designed to enable the stealing/leaking of state secrets would seem to be skirting pretty close to the line of "I'm just a private citizen/journalist." This is doubly true if said leaks end up putting military personnel and government assets in harms way.

We don't need to consider that possibility. It has been over a decade since this information was released. If anyone about whom USA government cares had ever suffered any harm (even if they actually deserved it) as a result, the USA war media would have crowed about it until we had all memorized all details. Not even a rumor exists of anything like that, so we know it didn't happen.
