Elon Musk is under scrutiny for backing an anti-Semitic post, but has not faced any sanctions in his 52-year career, according to crisis management expert Eric Dezenhall. Dezenhall suggests Musk's response will depend on his perception of the threat to his companies. Advertisers like Apple, IBM, and NBCUniversal have pulled ads from Musk's social media platform following the controversy. Musk has denied the allegations of anti-Semitism on the platform.
