jbrodkin writes "Cell phones are 'Stalin's dream,' says free software pioneer Richard Stallman, who refuses to own one. 'Cell phones are tools of Big Brother. I'm not going to carry a tracking device that records where I go all the time, and I'm not going to carry a surveillance device that can be turned on to eavesdrop.' Even the open source Android is dangerous because devices ship with proprietary executables, Stallman says in a wide-ranging interview on the state of the free software movement. Despite some progress, Stallman is still dismayed by 'The existence and use of non-free software [which] is a social problem. It's an evil. And our aim is a world without that problem.'"
