Leaking the intelligence budget was probably the most justified leak. Even if you want a geopolitically strong American government, the intelligence budget tells the public how much effort the USG puts into covert programs. So without it you can not have a meaningful debate about the size of the intelligence agencies. But on the other hand, I do not believe that other agencies can infer much from it, since everybody already knows that there is a quite big budget. So even in a real politics interpretation, the budget tells other intelligence agencies, how nice the chess board is, not what strategy is played.
