It's important to understand that this dump contains not only the fact that the CIA had this capability, but also the actual code that they used. Think about what that means.
1) WikiLeaks (and the leaker) have now given other governments, and generic hackers/thieves/bad guys/perverts, etc., the ability to do exactly what some folks are saying they don't want the CIA to do. It greatly multiplies the number of people who may invade our privacy, and makes all of us much less secure.
2) The average person lacks the ability to use this information to protect themselves. So, for most of us, this dump doesn't even have the offsetting advantage of making us even a little bit more secure.
3) Opposing governments and other sophisticated organizations (like some terrorist organizations) do have a greater ability to use this dump to protect themselves and/or modify their behaviors, to make effective surveillance less likely. In other words, this makes it much more difficult for our own government to get useful, actionable intelligence regarding bad people who actually mean to do us harm. For all we know, it may be the equivalent of telling the Nazis about Ultra, or the Japanese about Magic.
I cannot fathom the argument that this dump, and the person/people responsible for it, are actually a good thing.
