For news apps that offer subscription services, the App Store normally takes a 30 percent cut in the first year, then a 15 percent cut thereafter. However, DCN is arguing that Apple gave more favorable terms to Amazon with its Prime Video iOS app, taking only a 15 percent commission from the start — as revealed during recent congressional hearings. (Amazon founder Jeff Bezos owns the Washington Post, which is part of the DCN group fighting Apple’s fees.)

“We would like to know what conditions our members — high quality digital content companies — would need to meet in order to qualify for the arrangement Amazon is receiving for its Amazon Prime Video app in the Apple App Store,” Kint wrote. “I ask that you clearly define the conditions that Amazon satisfied for its arrangement so that DCN’s member companies meeting those conditions can be offered the same agreement.”
