Fiduciary duties have various requirements under the law, and it is not merely what the "company" might say that it wants.. so fuck that nonsense definition regarding what a fiduciary is.  In essence a fiduciary can still have a lot of discretion, but a fiduciary is also going to be subject to law suits from the company, shareholders or the government if it seems that the fiduciary is acting against the interests of the shareholders, for example.  I guess my point is that even if the fiduciary has obligations, a fiduciary also has a wide-range of reasonableness in carrying out its fiduciary duties, so I would imagine that Musk is way the fuck too childish in both what he wants to do than to be restricted by fiduciary duties, even if those fiduciary duties would still leave him with a lot of discretion.. but it would not allow him to be his typical self of being all the fuck over the place and making base-less requests regarding what he would like or not like and then flip-flopping all over the place unless he could establish some kind of reasonable basis (even if others might not agree with his reasonableness, but if he were to continue with his historical practices of all over the place nonsense, then he likely would end up putting himself in legal jeopardy sooner or later - probably sooner).
