When AT&T was asked politely by the NSA to open its networks under the warrantless surveillance program, the company refused to confirm or deny. They actually offered arguments like this one from an AT&T attorney:

Federal law may "authorize and in some cases require telecommunications companies to furnish information" to the executive branch, said Bradford Berenson, who was associate White House counsel when President Bush authorized the NSA surveillance program in late 2001 and is now a partner at the Sidley Austin law firm in Washington, D.C. Far from being complicit in an illegal spying scheme, Berenson said, "AT&T is essentially an innocent bystander."

And a sealed AT&T document I obtained tried to offer benign reasons why there would be a secret room at its downtown San Francisco switching center that would be designed to monitor Internet and telephone traffic: http://news.cnet.com/2100-1028_3-6077353.html

What Google and Facebook are doing today is precisely the opposite of what AT&T did.
