Wrong. Apple sells its software for an extremely high margin already.

When you buy Apple hardware, you are locked in to use Apple software and nothing else. A hardware vendor like LG/Oppo/Xiaomi would rely on Android, a commodity software, and thus, have very little pricing power against its competitors. Even though the technical specs of these phones might be better than the iPhone, they would struggle to sell for half the price.

The software lock is further amplified by those custom chips that are used across the Apple ecosystem. You're likely to pay exorbitant prices for the software on MacBook and iPad as well.

Remember, Apple usually doesn't touch a single phone throughout the manufacturing process (Most of the components are manufactured by third-party vendors squeezed into razor-thin margins). After paying these vendors off, they get to turn around and sell the same hardware for $600-650 more on the market. That wouldn't have lasted if they had licensed iOS out, their pricing power would be severely diminished.
