Richard Stallman is a computer programmer and founder of the Free Software Movement.
The idea behind the Free Software Movement is that computer programs should be able to be modified and redistributed without restriction. Free Software refers to free as in freedom to modify and redistribute. It does not necessarily mean "free" as in someone not having to pay for it. This leads to better quality software, and created more competition in the market. Stallman views the government and economy of the United States as extreme capitalism, where the corporations rule, and that we need to reestablish democracy. Richard Stallman created a Unix-like operating system known as GNU. There are many other free software programs that can be used as alternatives to conventional, corporate-made software.
Richard Stallman is a self-described liberal, and posts his notes on recent events on his website.
