Edward Snowden, a former U.S. spy agency contractor who leaked details of major U.S. surveillance programs, called on supporters at a hacking conference to spur development of easy-to-use technologies to subvert government surveillance programs around the globe.
Snowden, who addressed conference attendees on Saturday via video link from Moscow, said he intends to devote much of his time to promoting such technologies, including ones that allow people to communicate anonymously and encrypt their messages.
