Update not upon fictional evidence.

One man's fictional evidence is another man's thought experiment, and another's illustrative story.

To me, the lesson is "square dice are physical objects which imperfectly embody the process 'choose a random whole number between one and six'".

If you make the map-territory error and assume that "whatever the dice roll, is what we accept" while simultaneously assuming that "the dice can only each roll whole numbers between one and six; other outcomes such as 'die breaks in half' or 'die rolls into crack in floor' or 'die bursts into flame' or 'die ends up in Eliezer Yudkowsky's pants and travels unexpectedly to Washington DC' are out-of-scope", you're gonna have a bad time when one of those out-of-scope outcomes occurs and someone else capitalizes on it to turn a pure game-of-chance into a game-of-rhetoric-and-symbolcrafting.
