If you've seen their license then happy to be corrected but typically an architecture license wouldn't permit them to do precisely what they want with the ISA with no restrictions whatsoever.
I haven’t seen their license but they founded ARM and even though they don’t retain any ownership of the business I have heard that they retain a license that allows them to do pretty much whatever they like with the architecture in their own products.
