Elon Musk said Apple is behaving anticompetitively by promoting OpenAI’s ChatGPT while suppressing his Grok AI chatbot in the App Store, renewing his criticism of the iPhone maker’s partnership with OpenAI.

The response comes after Musk threatened to sue Apple via xAI, claiming the iPhone maker was “behaving in a manner that makes it impossible for any AI company besides OpenAI to reach #1 in the App Store.

In a statement to Bloomberg’s Mark Gurman, Apple insisted the App Store "is designed to be fair and free of bias," noting that it features “thousands of apps through charts, algorithmic recommendations and curated lists selected by experts using objective criteria” to ensure safe discovery for users and opportunities for developers.
