I agree that this is very different from traditional content agreements. Apple is a very conservative company. They may not want to be trailblazers when it comes to working out how compensation of creators is going to work in an AI context.
What appears to be happening right now is that Google, OpenAI, et.al. are negotiating individual agreements with large publishers if and when threatened with legal action.
I'm not sure this will be sufficient. There will be calls to introduce some sort of AI tax or other forms of collective compensation schemes to funnel money to independent creators, small businesses, museums, etc.
This is all very much up in the air and it will take many years if not decades to settle.
