"According to Assange," notes The Next Web, "it doesn't stop with Facebook. He believes
the social network is joined by Google, Yahoo and other major US organizations that have 'built in interfaces for US Intelligence.'" Said Assange: "It's not a matter of serving a subpoena, they have
an interface they have developed for US Intelligence to use. Now, is the case that Facebook is 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."
The Wikileaks founder goes on to warns Facebook users that if they add their friend to Facebook they are "doing free work for US Intelligence agencies, in building this electronic database for them."
