"I don't have a cell phone. I won't carry a cell phone," says Stallman, founder of the free software movement and creator of the GNU operating system. "It's Stalin's dream. 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."

Stallman firmly believes that only free software can save us from our technology, whether it be in cell phones, PCs, tablets or any other device. And when he talks about "free," he's not talking about the price of the software -- he's talking about the ability to use, modify and distribute software however you wish.

Stallman founded the free software movement in the early- to mid-1980s with the creation of the GNU project and the , of which he is still president.

ON BOARD:

When I asked Stallman to list some of the successes of the free software movement, the first thing that came up was -- not Google's version of Android, but rather a third-party version of the mobile OS in which all proprietary software has been stripped out.
