The bigger issue I think is when the prosecution of the CIA leakers happens. If the material is unclassified, they're just distributing materials that are public domain and definitely in the interest of the public. If it's classified, it's a breach and they should be punished in some way.
From the article it says that the files were circulating in the wild, so if this was not leaked to Wikileaks then "the bad guys" would continue using this and the public would not know.
