the Wikipedia article on this changed over the years (not looking for conspiracy theory here). About 2 years ago the lawsuit section was more detailed. It said something similar in logic to this article's title; the defendant replied that no room of such nature exists, BUT this lawsuit should be thrown out of the court because of National Security :)

It helps to imagine the scale of it if that existed for Google and Facebook.
