For all the free market cheerleaders, remember this: we already have laws in place preventing or regulating businesses from engaging in certain activities, like exploitation, gambling, addictive drugs, etc. And these companies fighting Apple want to do exactly that: Epic wants to sell digital gambling (loot) boxes to children. Facebook and Instagram want to track everything you do every second of the day, for the dubious goal of making advertising “more relevant to you” (and just happens to have the small side effect of being a tool currently in use to topple democracies around the world). Social networks are hooking into addiction centers of the brain to keep people hooked on misinformation that is actually killing people.
Is Apple perfect? No. Is this one thing going to stop all that I mentioned? No. But you have to start somewhere.
