Unless you can find proof of collusion I’m not sure it matters. Making matters worse the Google Play Store is completely optional you’ve been able to side load for years. To the degree Google prevented that they just got kicked in the teeth for it. So you’re going to have to argue that the combination of the Apple App Store, plus Google, plus Samsung, plus everything else all work together to screw over users. Good luck.
