I didn't see any new convincing arguments there. In fact, it seems to be based mainly on the claim that the thing inside that literally looks like a 2D Othello board is somehow not a model of the game, or that the fact that outputs depend on it doesn't actually mean "use".

In general, I find that a lot of these arguments boil down to sophistry when the obvious meaning of the word that equally obviously describes what people see in front of them is replaced by some convoluted "actually" that doesn't serve any point other than making sure that it excludes the dreaded possibility that logical reasoning and world-modelling isn't actually all that special.
