Elon Musk must face claims by OpenAI that his attacks on the startup in court and in the media amount to a “years-long harassment campaign,” a federal judge ruled.

The billionaire said in posts on X that the consumer tech giant was violating antitrust laws by giving preferential treatment to OpenAI on the App Store.

Musk threatens to sue Apple for allegedly favoring ChatGPT and blocking other AI rivals from the App Store's top spot. Altman notes that Musk was accused of juicing his own algorithm on X.
