Again, I don't doubt, but one has to ask whether the value of that data is in fact all that substantial to anyone of malicious intent - there would, I would think, be far, far easier ways to obtain that data and again, the volume of it here would likely preclude attempts to remove it wholesale - if someone wanted localised data, why not get it from the same (likely more vulnerable) source the NSA did?

Also once again, I would guess that those with intent to cause disruption, fear or harm (even dissent) would probably have an easier time of things a dozen other ways. In building secure systems, it's always worthwhile to gauge the value of some data to an attacker and the cost to them of obtaining it.
