> The point is that we should seek more robust systemic change than petitioning business owners to be better people against their best interests (finance, power).

No, that is not the point being raised by the majority of the “fiduciary duty” defenders. But even if we concede that’s what some are arguing for, that is such a bizarre stance to take: “we want the same thing, and but I’ll criticise you and shill in defense of the CEO because the way you’re doing it isn’t extreme enough”. That is absurd and it makes no sense to think the person criticising the CEO doesn’t also realise that more robust systemic change is desired and necessary. But you can’t do that all at once.
