Apparently Space X and Tesla both have entire protocols and teams specifically set up to minimize Musk's influence in the companies. I once read a story by somebody who interned at Space X who was told, as an intern, not to do anything Musk ordered him to do and to run it by his boss first. The reason Twitter is burning so badly is because there's no team there to run Musk damage control, so he's free to do whatever he wants and suffer the consequences.
