In a dubious achievement, Bob Iger earned the enmity of the world’s richest individual: Elon Musk. The billionaire was furious at Disney and its CEO after the company pulled its ad spending from Musk’s X (the social media platform formerly called Twitter).

The acrimony stemmed from Musk’s post on X on Nov. 15, “You have said the actual truth,” replying to someone who evoked the white-nationalist Great Replacement conspiracy theory that Jewish communities “have been pushing the exact kind of dialectical hatred against whites that they claim to want people to stop using against them.”

At the New York Times’ DealBook conference last month, Iger was asked about Musk’s comment. “I have a lot of respect for Elon and what he has accomplished,” Iger said. However, given “the position [Musk] took, in quite a public manner,” Disney concluded that its association with Musk and X/Twitter was “not necessarily a positive one for us.”

Later in the day at the same conference, Musk had a message to Iger and others who had halted ad spending on X: “Go fuck yourself. Go. Fuck. Yourself. Is that clear?” Musk said. He called out Iger and said, “Hey Bob, if you’re in the audience, that’s how I feel — don’t advertise.”

Musk wasn’t done fuming. Posting on X earlier this month, Musk cited a report that New Mexico’s attorney general sued Meta and CEO Mark Zuckerberg, alleging that the company’s platforms enabled the distribution of child sexual abuse material and failed to identify alleged predator networks. (A Meta spokesperson said that it uses “sophisticated technology” and employs child-safety experts to share information and tools with other companies and law enforcement, “including state attorneys general, to help root out predators.”) Musk accused Disney of a double standard in not pulling advertising from Meta.

“Bob Eiger [sic] thinks it’s cool to advertise next to child exploitation material. Real stand up guy,” Musk wrote in a post on X, misspelling Iger’s name. The tech mogul said in a follow-up post about Iger, “He should be fired immediately. Walt Disney is turning in his grave over what Bob has done to his company.” Disney has declined to comment on Musk’s remarks.

Meanwhile, Tesla has reportedly removed the Disney+ streaming app from its electric vehicles, in an apparent retaliatory move by Musk.
