The document discusses the WikiLeaks release of US diplomatic cables in 2010 and the subsequent response. Julian Assange, WikiLeaks founder, was detained in the UK awaiting extradition. In response to WikiLeaks, companies like Amazon, PayPal, MasterCard, Visa, and others cut off services to WikiLeaks. The hacker group Anonymous then launched Operation Payback, a distributed denial of service attack on the websites of these companies, bringing some of them down intermittently in support of WikiLeaks.
