Apple designs their software to work with their hardware and their EULA says as much. You want to use their products you subscribe to their licensing. Your argument of I bought it so I can do what I want with it has limits in every sector so to apply it here and not universally fails. If you buy a product with known limitations you are acknowledging that you will abide by those limitations through the act of ownership. If you don't want to follow those limits don't buy it. If you do buy it and still choose not to follow those limits then you are at fault if caught and have waved the right to cry foul.
