App permissions are an underrated feature of Apple’s ecosystem. You may even find them annoying if you’re bugged frequently by Bluetooth usage or app permission alerts. But they serve a purpose.
Without these permissions, third-party apps (or malware) have a much harder time using important parts of your system. This is true across pretty much any Apple product with app permissions built-in. It gives users a sense of agency and the ability to control what data and system features their apps can use.
