That 30% is specifically designed to be a little bit above the cost of running the system as a whole, but not much. As you point out, they really don't make much in the way of profit on their software or services -- almost all their profit comes from selling the hardware. So, 30% is just the cost of doing business in the ecosystem. If you don't like that, you don't have to participate in that ecosystem. It is entirely your choice.
