Interviews in the US are based around stock algorithms. Most media headlines in the US, particularly about companies, are for stock algorithms/fluctuations. “Buy the rumor, sell the news,” has been a classic adage for a while.

So really these interviews are basically ads. That’s why Elon isn’t being asked difficult questions about Tesla. If pieces come out trying to tank Tesla, they won’t usually include an interview. Trump, as an entertainer and business person, is used to this type of interview and expects it. Unfortunately, advertising doesn’t make for good journalism.
