tl;dr: Apple has sued OpenAI, io Products, and two former Apple employees—ex-VP Tang Tan and engineer Chang Liu—alleging they stole trade secrets to benefit OpenAI's hardware efforts led by Jony Ive. The complaint claims Tan solicited confidential info and Apple hardware samples from job candidates, Liu exploited a security bug to download thousands of pages of engineering files, and OpenAI tapped Apple suppliers using insider knowledge. Apple, which says over 400 ex-employees now work at OpenAI, is seeking damages and injunctive relief as OpenAI prepares its first consumer hardware device.
