Well, besides ARM, there is also MIPS core or ISA that IC makes can also buy a license and embed into their products in the same fashion as ARM.

They can also design their own ISA. An ISA is a document, they can write their own. Now, can you think of reasons why they wouldn't want to do it that don't also apply to MIPS?
