Trump is a mature strategist who is good at tolerance and compromise. Musk is quite unstable and fickle in temperament. Stand on the side of the Trump government and scold the Trump government. Who will like such team-mates? Even if they are wrong, they can communicate privately. It is a taboo to publicly scold. Musk ultimately always puts his own interests first. Some people in Trump's government go to prison for Trump. Can Musk do that? Absolutely impossible. When Musk publicly supported Trump, Trump had taken a big lead. Even without Musk's support, Trump could win. Loyalty comes first when standing in line, followed by ability. An unfaithful subordinate is more capable and dangerous for a leader.
