Why do people act like having “private APIs” is something evil? The entire purpose of having published public APIs is that they should be something that doesn’t change without a deprecation schedule or warning while the underlying implementation can change without notice. This is software engineering 101.
I don't know about evil, but it's hostile because Apple is intentionally preventing a non-AppleOS version from existing. The details of how they do it are of merely scientific interest.
It’s not hostile that you build a system with a public API that doesn’t change and private methods that you make no guarantees about. This is how software engineering has always worked.
