My feeling is that the fairness effect comes into play strongly with open source distribution models. People are willing to play fairly (i.e. not re-distribute source code that's probably only a google search away anyway) when the author does the same. Frans De Waal demonstrates an experiment with Capuchin Monkeys showing this effect in action. http://www.nature.com/nature/journal/v425/n6955/abs/nature01963.html http://www.nature.com/nature/journal/v425/n6955/abs/nature01... http://youtu.be/lKhAd0Tyny0 http://youtu.be/lKhAd0Tyny0
