Elon Musk has threatened to ban Apple (Nasdaq: AAPL) devices at his companies if the tech giant integrates OpenAI's technology at the operating system level. Musk, who serves as the CEO of Tesla (Nasdaq: TSLA) and SpaceX and owns social media platform X, expressed his concerns about the potential security implications of such a move.

During Apple's Worldwide Developer's Conference (WWDC) on Monday, the company announced plans to integrate its new AI software, Apple Intelligence, across its iPhone, iPad, and Mac product lines. Additionally, Apple revealed a partnership with OpenAI, which would allow the integration of ChatGPT, powered by GPT-4, into some of its software, including an improved version of Siri.

Musk, who co-founded OpenAI in 2015 but has since parted ways with the company, took to X to vex about the partnership. He said that if Apple moves forward with the OpenAI integration, he would ban Apple devices in his companies and visitors would be required to store their Apple devices in Faraday cages, which block electromagnetic transmissions.

The billionaire entrepreneur expressed doubts about Apple's ability to ensure the security and privacy of user data once handed over to OpenAI. He also criticized Apple for not being "smart enough" to develop its own AI while claiming to be capable of protecting user information.

This latest issue comes on the heels of Musk's ongoing feud with OpenAI and its CEO, Sam Altman. In March, Musk sued the company, accusing it of betraying its original mission of being open-sourced and developing artificial general intelligence (AGI) for the benefit of humanity. 

Since then, Musk has launched his own rival AI company, xAI, and a ChatGPT alternative called Grok. xAI raised $6 billion in its series B fundraising round, and Musk was accused of using Tesla data to help sell it to potential investors.
