True. I have tried fixing transmissions and they are difficult.
But anybody running a company sets the vision. They can hire people execute the vision, but need to know and express the idea about what they want. It isn't clear that musk has any idea about what he is doing. He paid way too much money for a company loosing as much money as twitter is. Eliminating free lunches isn't going to save it and will drive some employees away.
Alienating commercial subscribers will not help either. I am not a known stockholder.
