No they don’t. I mean, that is why they have that license (though PA Semi, the company they absorbed that develops their cores, also brought one along with them); but it’s not a special or unique license. Nvidia, Qualcomm, AMD, etc all have the same license.

Apple is near unique only in that they’ve pretty much never used reference implementations (since the PA Semi acquisition, at least) from ARM and stick to their pure bespoke microarchitectures. But they’re not the only company that could.
