Let's take away the ethics and social impacts of free software for a second, and let's see free software and and propietary software as evolving information species in a darwinian world, our culture, fighting for the same resources.
Free software follows a
meme evolution. Propietary software follows a secrecy method. Which sounds like a more succesful method of evolution? Which species will outrule the other eventually?
Even farther, which is a more natural approach and blends best with the environment?
"
The whole idea of a meme is that it's information that is copied with variation and selection. So any idea that is copied from person to person is a meme. But an idea that you think up for yourself and is not expressed is not a meme. The emphasis has to be on copying, because that's what makes evolution possible. Lots of ideas are never copied at all. They just go to a couple people and then they fizzle out."

Being free and making information free... is human nature, we are just machines to propagate memes.
