Many thanks to Lauren Alder for pointing me towards this expose of The Guardian‘s post-Snowden, friendly relationship with British spydom. According to the report, The Guardian has accepted, for the past five years, a seat at the table of British spies and bureaucrats who decide which secrets must be kept hidden from public gaze. A far cry from the image the paper crafted at the time of the Snowden revelations.
You can read the article and various supporting tweets by Matt Kennard, here and here. His report, largely based on leaked British documents, suggests that The Guardian, which accepted a seat on the D-Notice committee that censors state secrets as long ago as 2014, has agreed with its new friends in Whitehall to pass on security advice, i.e. what stories not to report, to other outlets, including The New York Times.
By the way, here is a link to Matt Kennard’s Wikipedia profile.
