x86 architecture is their core product (or rather the foundation for their core products), so they problably try to push it forward whenever they can, like Windows for MS (Windows Phone on a device without any actual windows...). It's what they do for thirty years, so I suppose they think it's part of their DNA and will fail if they try anything else.
