Elon Musk has escalated his feud with Sam Altman by threatening Apple with legal action over alleged antitrust violations, claiming that the App Store favors OpenAI's ChatGPT over his Grok chatbot. The dispute arises amid ongoing tensions stemming from Musk's exit from OpenAI and his criticisms of Altman’s management of the company. Altman retaliated by suggesting Musk’s accusations are hypocritical given his own manipulations of social media algorithms.

Elon Musk announced that his AI startup xAI will take legal action against Apple, alleging antitrust violations related to App Store rankings. Musk claims Apple's practices favor OpenAI's ChatGPT, making it difficult for other AI apps, like xAI's Grok, to compete for the top spot.
