Fiduciary responsibilities can be construed very broadly, and as long as they can point to CEOs with similar salaries and haven't recorded themselves basically admitting to some illegal arrangement it's extremely hard to do anything about it unless you'd been a shareholder.
That may be true, but i also think its pretty unfair to claim, even just on the internet, that the board is inapropriately setting compensation based on a conflict of interest without some evidence its true or at least some evidence that said compensation is unusual.
