You don't have to be an Apple customer to be affected by Apple's anticompetitive business practices. Apple's actions affect the whole market and all consumers in that market, that's the point behind antitrust law and litigation.
Easily, Apple and Google collude to maintain dominance in the mobile OS markets and leverage that duopoly to dominate other markets like mobile app distribution and mobile app payments. Google's app payments policy is now nearly identical to Apple's, you must use their payment platform to distribute apps on their app store. Just like Apple's policy to prevent competition in the mobile app payments market prevents app developers from even mentioning alternative payment methods in apps or app store listings, Google quickly followed suit and implemented the exact same anticompetitive policy.
Yes, it's just a coincidence that Apple and Google's anticompetitive policies in the mobile OS and app distribution markets have converged such that they are both practically identical and also allow them to leverage their dominance in those markets to dominate other markets like mobile app payments, as well.
