No, that paragraph describes the duty of officers of the company to put the interests of the company before their own. It doesn’t claim that these officers need to behave unethically. You could even argue that displaying unethical behavior is not in the best interests of the company in the long run but this is of course hard to prove in any direction.

You asked for a citation of fiduciary duty. I already explained why that precludes moral action in this case

I now realize I misinterpretted your prior reply as copypasta of the "maximize shareholder value" trope.

My apologies.
