Even if James Murdoch is entirely amoral and more of an abacus-bean-shifter (i.e., money guy), we must recognize that the reason why an electric car company like Tesla even exists is because of headstrong founders and employees who demanded a sustainable form of transport that was not just excellent among electric cars, but one of the greatest cars.
In a way, money guys getting into Tesla is validation of the mainstream viability of sustainable transport, but we are still in a fragile state where all kinds of forces are aligning themselves against Tesla. We still need people ideologically committed to a rapid sustainable transition.
