Exactly. I'd be careful about wikipedia, anyone can post and alter information that's there. I imagine topics like this would get worked over by any number of individuals for all sorts of reasons.

Under the Secretary of Defense, and in accordance with approved policies of USCIB, the Director of NSA shall be responsible for accomplishing the mission of NSA.

Quoting from the website:
"Three major intelligence agencies in the Department of Defense (DoD) - the National Security Agency (NSA), the National Reconnaissance Office (NRO), and the National Geospatial-Intelligence Agency (NGA) - absorb the larger part of the national intelligence budget. NSA is responsible for signals intelligence and has collection sites throughout the world. "
Nevertheless, given that NSA is tasked with "signals collection" this doesn't sound like their playing field to me.
