During an interview with Russia Today, Assange said "Facebook in particular is the most appalling spying machine that has ever been invented."
Assange, who surprised the entire world by releasing United States' confidential cables through WikiLeaks, said that Facebook provides all essential details about people to various intelligence agencies in United States.
"Here we have the world's most comprehensive database about people, their relationships, their names, their addresses, their locations, their communications with each other, their relatives, all sitting within the United States, all accessible to U.S. intelligence," Assange said.
Assange alleged that major tech companies in United States are helping the government to know about people.
"Facebook, Google, Yahoo, all these major U.S. organizations have built-in interfaces for US intelligence. It's not a matter of serving a subpoena. They have an interface that they have developed for us intelligence to use. Now is it the case that Facebook is actually run by US intelligence? No it's not like that. It's simply that US intelligence is able to bring to bear legal and political pressure to them and it's costly for them to hand out records one by one so they have automated the process," Assange alleged.
Furthermore, WikiLeaks editor said that when somebody add their friends to Facebook they are doing free work for United States intelligence agencies.
"Everyone should understand that when they add their friends to Facebook they are doing free work for United States intelligence agencies in building this database for them," Assange said.
