I think it is defensive. But most of the SoC market is using Arm processors these days since it is easier to buy it than develop it and the related software infrastructure. Most OEMs prefer it.

The Japanese companies were the original Asian tiger who gave consumers advanced technology with intuitive interfaces. Today, Apple tends to wear that crown. And tomorrow is an open question.
