Yeah, Phil Zimmerman's article mostly addresses intercepting vulnerable transmissions over a wire or through the air waves.
Not so much about breaking encryption, and attacking a static target.
I think Phil Zimmerman's assumption (at least, withing the context of this article) is that if you're attacking an sample of encrypted information, that act alone comes with the implicit understanding that you're probably acting against the interests of the person who locked the information away in the first place. Whether that person or group of people are worthy of the attack is its own judgement call.
