Apple is not doing that. As the article describes, the issue is that your avatar (during a FaceTime call, for example) accurately reproduces your eye movements.

This is a great example of why ‘user-spacey’ applications from the OS manufacturer shouldn’t be privileged beyond other applications: Because this bypasses the security layer while lulling devs into a false sense of security.

I don't think that's an accurate description, either. The SharePlay "Persona" avatar is a system service just like the front-facing camera stream. Any app can opt into using either of them.
