Intel is an ARM architecture licensee.

Ah, I should have checked. I did read through the ARM architecture page† on Wikipedia and it does not mention that fact. It does say,

"In 1994, Acorn used the ARM610 as the main central processing unit (CPU) in their RiscPC computers. DEC licensed the ARM6 architecture and produced the StrongARM. At 233 MHz, this CPU drew only one watt (newer versions draw far less). This work was later passed to Intel as a part of a lawsuit settlement, and Intel took the opportunity to supplement their i960 line with the StrongARM. Intel later developed its own high performance implementation named XScale, which it has since sold to Marvell."

I'm not sure how much sense it makes for Intel to be both an ARM licensee and develop Atom.

I believe they sold that license about the time they went for Itanic.

It wouldn't be smart of ARM to help Intel and harm it's own ecosystem and especially the chip fabs,because once they are weakend enough, Intel could return to using it's own cores.
