Most of the apps I install are mandatory apps. It's not illegal to not have them, but if you don't install you can't access your doctor, file an insurance claim, bank, see your childs grades, enter the front door of your child's preschool, etc. All of these are malicious actors who will steal as much of my data as possible at all times, but I do actually need a preschool. As long as I can only install these through the app store, we are at an uneasy truce where these apps comply with app store rules.
