iTunes doesn't exist to sell music. iTunes exists to give you a reason to buy into, and/or stay in, the Apple ecosystem - to wit, sell Apple hardware.

They're not going to prevent it (ex.: someone buying & playing music on iTunes on Windows), but they understand that everything they do must serve the core: sell hardware.
