To think that in the response letter from Apple one could find anything but reasonable statements would be very naive. That letter has been drafted/reviewed by high skilled lawyers and, as much as one does or does not agree with the points they make, it still makes some clearly outlined arguments. So what I find most interesting is what it's not there. They do not mention once the fact that their own streaming app can compete on better terms since they do not have to give away 30-15% of the subscriptions.
