The Guardian had been put in a position it never wanted. Its liberal reputation, and previous disclosures, had made it the newspaper of choice for WikiLeaks’ and Snowden’s revelations.

It therefore rolled over when the government told it to cease and desist, before taking its place alongside the rest of the right-wing media on the secret committee responsible for press censorship and propaganda dissemination.
