OpenAI just did something you almost never see in corporate legal disputes: it published private iMessages and emails to publicly embarrass a plaintiff. The target? Apple. The occasion? A trade secrets lawsuit that OpenAI is calling "careless, aggressive, and oddly personal."
Here's the backstory. Apple filed suit last month against OpenAI and two former employees — Chang Liu and Tang Tan — alleging they walked out the door with confidential information about unreleased Apple products and technologies. Liu was an iPhone engineer. Tan spent 25 years at Apple, including a long run overseeing iPhone and Apple Watch hardware, before becoming OpenAI's chief hardware officer. Apple wants a preliminary injunction to immediately block all three parties from using, sharing, or even accessing any alleged confidential information while the case plays out.
OpenAI's response was not a legal filing. It was a blog post. And that's a deliberate choice worth paying attention to.
Rather than letting its lawyers handle this quietly, OpenAI went straight to the public with a counter-narrative and receipts to back it up. The company's core argument is that Apple is misrepresenting what actually happened with Liu's post-departure access to Apple's internal systems. Apple frames it as Liu exploiting an authentication vulnerability to access cloud storage after he left and downloading sensitive files. OpenAI frames it very differently — arguing that Apple's own employees reached out to Liu after he departed and asked for his help locating information, and that residual access to company systems after an employee leaves is a known, systemic problem Apple hasn't fixed.
That's a meaningful distinction. If accurate, it reframes Liu less as someone who went out of his way to steal data and more as someone Apple's own team kept pulling back into their systems even after he tried to leave cleanly.
It's also worth noting what OpenAI is not saying. The company isn't disputing that Liu had access to Apple files or that Tan held a senior role with access to sensitive product information. It's disputing intent and context — harder things to prove, but also the things that tend to matter most in trade secrets cases.
The move to go public with private communications is a calculated risk. OpenAI gets to shape the narrative before Apple does, potentially influencing how the press and the public — and maybe eventually jurors — understand the case. But it also signals a combative posture that could complicate settlement talks down the road.
The bigger picture here is that this lawsuit is really about something Apple cares deeply about: its hardware future. Apple has been aggressively building out its AI infrastructure, and losing senior hardware talent to the company it just partnered with on Apple Intelligence is a genuine competitive concern. Whether that concern rises to the level of a legitimate legal claim is now for the courts to decide — but OpenAI is clearly not going to let Apple set the terms of the public debate while that process unfolds.
