I'm not sure that's true though..
With the way Apple operates, we have ten years before we can reasonably assume that they would change their architecture. Is RISC-V really going to be worth all the headaches of a transition in ten years?
"The company was founded in November 1990 as Advanced RISC Machines Ltd and structured as a joint venture between Acorn Computers, Apple Computer (now Apple Inc.) and VLSI Technology."

More details about ARM licensing:
"Finally at the top of the pyramid is an ARM architecture license. Marvell, Apple and Qualcomm are some examples of the 15 companies that have this license."

I can bet $100 on it being wrong. Especially the ARMv8 ( and v9 )
Long story short, it's probably not terribly utilitarian to have strong opinions about the subject when participating in an international forum such as this one.
