“If utilitarianism is the correct moral framework, the answer is simply to pull the lever and spare the most lives” that’s the reason why it’s a critique. If utilitarianism aligned with human morals, then there’s no question on what action a moral person would perform. Except it’s nothing but endless debate on what one would do in that situation. Thus it being a critique.

Not a great critique in my opinion. It’s like how Schrödinger’s Cat, a critique on the absurdity of superpositions, is now just there as a stand-in for the weirdness of quantum mechanics. A critique should be clear on what is attempting to accomplish.

To be fair, though, humans will twist critiques of something into advocacy, even if it’s tone deaf as hell. Defending bad cops as “a few bad apples” when the rest of the phrase is “spoils the bunch”. Or “pull themselves up by their bootstraps”, a thing which is impossible, being used to express frustration towards the poor.

Maybe v1.0 was. It has developed into more than just one thing in the intervening years.
