Buffet has complained about how he has to be subtle to move in or out of positions because he is so big he creates his own weather. He seems to care whether he makes money from making good choices versus brand recognition. It sounds like he has to use third parties to do big moves and of course they are going to want to take a bite. Nobody is going to move millions of dollars of inventory for you out of the goodness of their hearts.
Someone who does not give a shit can do a lot of damage without technically breaking the law.
