The leadership team absolutely does not have any responsibility to maximize short-term profit, whichis the claim this thread is about.

It has a responsibility to not actively and intentionally destroy the company, and to not use the company's resources for purely personal gain in a way unrelated to the company.

That's it.

This is also why you never hear about any company getting sued for anything related to this (let alone succesfully). Because it doesn't happen, as it's not a thing and any lawyer would immediately tell you you don't have a case.
