The entire premise of Apple is building highly tuned private APIs. It’s what makes things like Apple Silicon battery performance and power to watt ratio possible. This kind of super fine tuning is practically impossible over a public API boundary, or at least much more difficult task. Take Live Translation for example. It has very tight latency and performance requirements which would be hard to make work over a public API where you can’t control the other device. Many types of audio applications are literally impossible to build on non-Apple devices due to the latency requirements. There is an entire audio ecosystem that cannot exist on Android due to the realtime performance requirements.
