It would be like if you went to best buy (or whatever electronics store is in your country) and bought a washing machine. This washing machine (in small print no less) has "in-home purchases" that let you change the modes to include color and whites instead of just a "do it all eco-mode." Best buy takes 30% of all these "in-home" purchases because they sold you the washing machine. They assert that you are their customer and you are not the owner of the washing machine. Oh, and you can't share this "in-home purchase" with anyone else that lives with you. If they want this feature, they have to pay for it separately.

If that makes sense to you ... then I guess there isn't much to discuss here.
