Thank you for confirming what an incredible deal iOS developers are getting for a mere 30% fee. It sounds like Apple has created a really valuable platform that attracted wealthy customers compared to the competition and they should be rewarded for it.
It also confirms that because of Apple's dominance in terms of profitable smartphone platforms to develop for, developers are essentially obligated into having to support iOS if they want to make money. Even if you choose to spin that in a positive light, it demonstrates a power asymmetry.
