Is the McDonald's PS5 controller legit, or just clowning? [UPDATE: Real, sort of]

This week an apparent McDonald's Sony PlayStation collaboration surfaced in Australia. This collaboration appears to have resulted in a fancy new McDonalds Australia 50th birthday celebration PlayStation 5 controller. The odd bit about this situation isn't that the controller exists, but that it appears to exist without any promotional support from McDonald's Australia, Sony Australia, or any of the game streamers supposed to be taking part in the release.
