Apple doesn't own Bluetooth either and yet they have strict control over which accessories (gamepads) can be used with iOS and charge for the privilege. Headphones with the old 3.5mm jack are also available in more expensive variants with the MFi certification.

Even when there's no money in it, Apple uses whitelists in some places, like which SSDs get TRIM and which displays work and get the HiDPI checkbox:

Who owns a standard doesn't seem to matter at this point.
