Wikipedia is one of many tools used by the US liberal establishment and its allies in the intelligence community to wage "information warfare," the site's co-founder, Larry Sanger, has told journalist Glenn Greenwald.

Speaking on Greenwald's 'System Update' podcast, Sanger lamented how the site he helped found in 2001 has become an instrument of "control" in the hands of the left-liberal establishment, among which he counts the CIA, FBI, and other US intelligence agencies.

"We do have evidence that, as early as 2008, that CIA and FBI computers were used to edit Wikipedia," he said. "Do you think that they stopped doing that back then?" 

Activity by the CIA and FBI on Wikipedia was first made public by a programming student named Virgil Griffith in 2007. Griffith developed a program called WikiScanner that could trace the location of computers used to edit Wikipedia articles, and found that the CIA, FBI, and a host of large corporations and government agencies were scrubbing the online encyclopedia of incriminating information.
