The New York Times article shows how extensively AT&T cooperated with the NSA, noting that in 2013 "The company installed surveillance equipment in at least 17 of its Internet hubs on American soil, far more than its similarly sized competitor, Verizon. And its engineers were the first to try out new surveillance technologies invented by the eavesdropping agency. One document reminds N.S.A. officials to be polite when visiting AT&T facilities, noting, “This is a partnership, not a contractual relationship.” The documents also confirm what EFF’s Jewel v. NSA lawsuit has claimed since 2008—that the NSA and AT&T collaborated to build a domestic surveillance infrastructure.
