You don‘t seem to understand the issue. Not Apple is the issue, it‘s iOS. Any app(lication) on iOS and both macOS needs system-level permission in order to access location data, contacts, photos, and more. This is the foundation of its privacy and security system, and it works. The base setting on macOS is to only allow installation from trusted and verified developers, and that is a steong additional security enforcement as well. In order to install (supposedly) scammy apps by unknown developers, you need to apply a lot of hassles and workarounds to put them on your system, and while on this way you are asked tenfold if you‘re sure you want to carry the consequences. Which, btw, still cannot include access to things like files, contacts, photos, camera/mic, and so on.
What is talked about here is iOS where Apple dictates even the nature of apps that are allowed into the App Store, which does lower competition and applies censorship only (bad actors which track you nevertheless you kindly „asked“ them not to are still there, and scammy and copycat apps too - they just have a review team that evidently fails to provide its suggested security and app developers need public attention in order to have them rightfully let their apps into the land of glory).
You cannot install apps that evidently provide you with more control and security where even the OS fails (Little Snitch), you can‘t install apps with what you can do both good and bad (torrenting; it‘s like forbidding to use knifes in the kitchen because you could use them to harm others) and you can‘t install apps that fall into the allowed categories that Apple enforces on you (such as encrypted messaging apps in human rights-abusing countries, or news apps which report about government violence or abuse).
Feel free to pinpoint this all to greed and third-party app stores, but Apple actually supports such abuse with this. People need tools like Little Snitch to make sure their traffic doesn‘t get sniffed and torrenting is decentralized so people may use this in addition to VPNs in Myanmar, for example.
