Were you reading another article? The author of this one is not "calling for power to be moved away from people and centralised". Nothing like that argument at all appears in the article.
They are you're just ignoring it. 'Morality' is always presented in a binary context of morale/immoral and many of the examples in the article fall into the same pattern. You don't need to advocate centralizing power when discussing moral frameworks because it's implied in the conversation that hypothetically power will be centralized around the 'moral' viewpoint. For the same reason all morals are inherently supremecist because if they weren't they wouldn't be labeled the moral course of action.
