"Now, for beings that can think and learn, sharing useful knowledge is a fundamental act of friendship. When these beings use computers, this act of friendship takes the form of sharing software. Friends share with each other. Friends help each other. This is the nature of friendship. And, in fact, this spirit of goodwill -- the spirit of helping your neighbor, voluntarily -- is society's most important resource. It makes the difference between a livable society and a dog-eat-dog jungle."

Richard M. Stallman
