This is 100% what I'm saying. I think that it does fully justify the rule that people are saying is "unfair". I have yet to hear a good argument that doesn't amount to something totally incorrect like "Apple doesn't provide any value and is just a middleman" or just an opinion like "Apple shouldn't take part of the purchase just because they own the platform" because while it may be a valid opinion, it looks at the situation from only the perspective of the 2 companies in question (Apple and whoever) and not the end-user.
