This is the way I see the GPL: You own a bakery and sell Apple pie's. Your mother gave you the recipe that everyone loves, but you keep the recipe to yourself so people will keep coming to your bakery and because you think your mother's recipe is quite awesome. One day you are walking down the street and see a sign that says FREE Apples. You think, great I could use these. However, underneath the sign it says "By using this Free apple you must give the recipe of pies that were made with this Apple to anyone that eats it."

It bothers me when the GPL group uses the word Free, whether it's in Beer or Freedom because it's neither.
