This assumes that Trump is actually able to make decisions. He's clearly showing signs of dementia, and so he's easily controllable. His handlers just make sure he forgets anything they don't want him to remember.
Do you think Trump of 8 years ago would have allowed Musk to usurp the news cycle? Or even allowed the merest notion that he's not controlling _everything_?
Remember, Trump actually underwent a colonoscopy without sedation to avoid relinquishing the control of the nuclear weapons to Pence. This dude is a control freak.
