Even Chat GPT understands the point:
When you buy an iPhone, you own the physical device. However, the software that runs on the device is owned by Apple and is licensed to you. This means that Apple retains control over the software and has the right to dictate how it is used.Apple's control over which apps can be installed on an iPhone is based on the terms of the App Store, which is the only official way to download and install apps on an iPhone. When developers submit their apps to the App Store, they must follow Apple's guidelines and policies. Apple reviews each app to ensure that it meets its quality and security standards, and can reject apps that violate its guidelines.While some users may find this level of control restrictive, Apple argues that it is necessary in order to maintain the security and integrity of the iOS ecosystem. By controlling which apps can be installed on an iPhone, Apple can ensure that users are protected from malicious software and that the overall user experience is consistent and reliable.
