“Walt Disney is turning in his grave over what Bob has done to his company,” Musk wrote in a series of tweets directed at the media behemoth.

It comes only a week after he warned businesses that participated in an ad boycott of his platform, formerly known as Twitter, to “Go [expletive] yourself.”

Some businesses have stopped advertising on X due to antisemitism fears.

On Friday, Disney did not immediately respond to a BBC request for comment.

Mr Iger made a surprise comeback to Disney just over a year ago, less than a year after retiring, to guide it through challenging circumstances, as its share price plunged and streaming service Disney+ continued to lose money.

During his tenure at the firm, he has been credited with pushing major acquisitions involving the likes of Pixar, Marvel Comics, Rupert Murdoch’s 21st Century Fox, and Lucasfilm, the home of Star Wars.

These moves, together with the establishment of amusement parks, helped the company’s market worth more than fivefold.

Mr Musk appeared to allude to the poor box-office performances of some Disney corporations in a Thursday post, claiming Mr Iger unleashed “more bombs than a B-52”

The billionaire also accused Disney of promoting on other social media platforms that permitted provocative content.

Mr Musk lambasted advertisers who had abandoned X and warned that they would kill the social media platform in a profanity-laced outburst last week at an event in New York.

He also accused firms such as Disney, Apple, and Comcast of attempting to blackmail him by halting advertising on the site.

“I don’t want them to advertise,” Mr Musk stated in response to a question at the DealBook Summit hosted by the New York Times.

“If you’re going to blackmail me with advertising or money, you should [expletive] yourself.”

“Go. [Expletive]. Yourself. Is that understood? That’s how I feel, Bob, if you’re in the crowd.”

Mr Musk was probably referring to Mr Iger, who spoke earlier in the day at the summit.

Linda Yaccarino, CEO of X, who also attended the summit, has now tweeted what she dubbed Mr Musk’s “candid interview.”

She said, “X is standing at a unique and amazing intersection of Free Speech and Main Street — and the X community is powerful and here to welcome you.”

Mr Musk has been in Israel since last month, when he appeared to directly support an anti-Semitic conspiracy theory. He claimed the tweet was antisemitic but apologized, claiming it was the “dumbest” thing he had ever shared on the internet.

Many advertisers, however, have already decided to spend their money elsewhere.

Mr Musk admitted in a post on X in July that ad income had dropped by 50%.
