I apologize in advance for stretching the analogy so far here. But going back to my example, my son now goes into Walmart for a lemonade. The Lemonade stand is half the price, so he goes there. How do I know the lemonade isn't poisoned? Made with peanuts and not labeled as such? etc.. The argument would be that he doesn't have to go there, but that's easier said than done. I go to Walmart because I know that they verify their products. Going back to an iPhone, the answer is usually "you don't have to use any other app stores". But what about if I _do_? What if I have to use the new Coronavirus test that requires an app? And the only way to get the app is to install Abbott's app store? Are you guaranteed that they aren't also consuming all your health information? My view would be different if Android didn't exist, or if iPhone had a much higher market share. But for now, I'm happy to pay extra to be in the walled garden, because I trust the king of the castle to try to protect me (as opposed to figuring out who to trust out on the street).
