Yeah, I mean what is “all”? In terms of internet traffic, my understanding is that the NSA would have access to a significant fraction of all of it via this room (and perhaps others). A significant enough fraction that there’s a high likelihood any given internet communication could be intercepted. Maybe not every time but enough stuff routes through the US that eventually it will be seen. So to me I’ve feel comfortable using “all” in a loose (empirical) sense. But I see your point that it’s not as clear.
