Here is the most recent audio interview with Richard Stallman. In it he introduces the basics of the Free Software philosophy, but in a further discussion also explains some other interesting things such as the fact that Free Software is actually more in accord with the free market capitalism than proprietary software, the reduction of freedom that is going on in the world (specifically mentioned US and UK) and also Stallmans motivations for advocating freedom.
The Free Software Foundation acts as the benevolent force guiding the computer industry. It protects the users of software from the baddies, the list of which very often includes the names Microsoft, Apple, and TiVo.
But what happens when the benevolent force transforms into something of a hypocrit?
