Apple was one of the codevelopers of the arm6 and at that time Acorn spun out ARM holdings to create the ARM of today - so while architectural licences might come with restrictions, Apple most very likely have even deeper rights into the ARM ecosystem, up and including - "if you don't let us make the M1, we will deep 6 the entire arm ecosystem and use our "cocreator" patents offensively" It's easy to forget that Apple is/was one of the original computer companies, and had a founding hand in two ISA/architectures: PowerPC and ARM. They also used the Motorola 68000 and x86 (32+64), but in those cases they were relying on the manufacturer for the chips and architectural direction.
