This is a very old and proven method of marketing. A good example of this is still in use today. Crack Dealers. Give your crack away to children, so they become dependant on it. Once they are completely addicted, you have created a demand. Which allows Microsoft to continue business with little fear of anyone thinking any differently then they want. Because no addicted customer is going to revolt against their crack dealer. But they will introduce their friends and family to crack, and continue the cycle.
