The market down the street and Starbucks will decry the hippie for trying to prevent them from using his beans. But they are his beans and he has every right to set terms and conditions of sale. His goal is that those who do receive his beans and make special blends, etc. will give the same freedom to those who end up drinking the coffee as they have with his coffee beans. If the hippie's goal is coffee drinker freedom, he is likely going to leave the world a better place. If his goal is spreading his beans far and wide regardless of the restrictions on the coffee drinker at the end, he won't reach his goal.

(Or am I imagining a GPL vs BSD analogy?)
