If I understand correctly, the article says the "maze" was actually the many rooms of the Cretan palace. The word "labyrinth" comes from the sacred ax called "labrys" used to kill the bulls during sacrifice. The minotaur was an invention symbolizing a foreign power that Athens fought with and will overcome?

The big problem that the article glosses over is that "labrys" is neither Minoan (to our limited knowledge) nor Greek, but Lydian: the Roman-era author Plutarch in Ætia Romana et Græca tells us that the Lydians call the double-headed axe λάβρυν, and people have assumed that it must have a nominative λάβρυς. The Lydians lived in Anatolia, not Crete. The Carians, another Anatolian people neighboring the Lydians, had a place called Labraunda, and coins minted there in Roman times have a double-headed axe, but that's more than a thousand years after the Cretans. There's no good evidence that the Minoans knew the word "labrys" or connected it to axes or the labyrinth. Moreover, it's not clear that the axes we have were or could have been functional rather than votive or ornamental, as most are thin and weak, so assuming that they were used to kill bulls is a stretch.
