I have to admit I assumed this was going to be about Jony Ive but sounds like he's not part of the suit. Axios article talks about some specific claims:

> The lawsuit alleges that Chang Liu, a former senior electrical engineer at Apple kept a work-issued Apple laptop and discovered a bug that allowed him to access Apple's cloud file storage after leaving and while employed by OpenAI. Liu celebrated the exploit, according to the filing. "LOL, I found out I can access the [network storage], so funny," he said in a message to a former colleague who was still employed by Apple.
