The charge was not that the idea is not useful, nor that it is not true, either of which might be a mark against it. But "non-Bayesian"? I can't unpack that accusation in a way that makes it seem like a good thing to be concerned about. Even putting aside that I don't much care for Bayesian decision-making (for humans), it sounds like it's in the same family as a charge of "non-Christian".
