Stallman gave an extensive interview, where it spoke about the v2 and v3 versions of the GPL, Bill Gates, software patents and licenses, among other things:
Here is what Bill Gates said in 1991, in a leaked internal memo, about how software patents would have affected Microsoft's chances of getting started:
Gates, 1991: "If people had understood how patents would be granted when most of today's ideas were invented and had taken out patents, the industry would be at a complete stand-still today. The solution [...] is patenting as much as we can [...]. A future start-up with no patents of its own will be forced to pay whatever price the giants choose to impose. That price might be high: Established companies have an interest in excluding future competitors."
It's an interesting read for people who are new to Free Software and are not familiar with Stallman. There's also a short explanation about GNU Affero GPL, which I had never heard of.
For a better look at rms's background, there's always the free book, Free as in Freedom, also hosted at O'Reilly.
