Apple's OpenAI Dragnet Just Grew to 40 Ex-Employees — And It's Not About ChatGPT

The short version

Apple sent legal preservation letters to roughly 40 former employees who now work at OpenAI, ordering them to hold onto documents tied to its trade-secret case. That’s a big jump from the handful of people named in the original complaint, and it tells you Apple thinks the alleged leak is wider than it first claimed. My read: this fight is about hardware, not chatbots.

What actually happened here?

Apple escalated its trade-secret lawsuit against OpenAI by sending legal letters to around 40 ex-Apple staffers who have since moved to OpenAI, instructing them to preserve documents and communications that could become evidence. That number matters. When a company sends preservation letters that broadly, it isn’t fishing anymore. It’s signaling that it believes the alleged misappropriation reaches far beyond the individuals it originally named, and it wants a paper trail locked down before anyone hits delete.

The case first centered on a small group, including former Apple executive Tang Tan and engineer Chang Liu, both tied to Apple’s hardware and design world before they left. Now Apple is casting a much wider net across 40 people, which changes the shape of the whole dispute. You can read the full breakdown in the MacRumors and Financial Times report, which was the top story on Hacker News the day it broke. When a lawsuit becomes the number one item on HN, it usually means engineers smell something bigger than a legal footnote.

Why do I think this is about hardware, not AI?

Here’s the part that caught my eye. Everyone wants to frame Apple versus OpenAI as a war over artificial intelligence, because that’s the sexy narrative. But look at who Apple is chasing. Tang Tan wasn’t a chatbot guy. He was deep in Apple’s product hardware organization, the kind of person who knows how iPhones and wearables get designed, sourced, and built. Chang Liu came from a hardware-adjacent engineering background too. And the company these people are alleged to be feeding into, io Products, is OpenAI’s hardware venture, the one tied to Jony Ive’s design ambitions.

String those facts together and the picture stops being about who has the smarter language model. OpenAI is trying to build a physical device, some new category of AI gadget. The one company on earth that knows how to turn a wild industrial-design idea into a hundred million shipped units is Apple. So if you’re OpenAI and you want to skip a decade of painful hardware learning, the fastest shortcut is people who already lived it. Apple clearly believes that’s exactly what happened, and the 40-person dragnet is its way of saying the knowledge transfer wasn’t limited to two names.

That’s the original beat here: the size of the preservation list is the tell. Two engineers can carry ideas in their heads. Forty people carry processes, supplier relationships, manufacturing playbooks, and the muscle memory of shipping hardware at scale. Apple isn’t worried about a leaked prompt. It’s worried about someone rebuilding its hardware operating system inside a competitor.

What is a legal preservation letter, and why does the count matter?

A legal preservation letter is a formal notice telling someone they must not destroy documents, emails, messages, or files that might be relevant to litigation. It’s a defensive move as much as an offensive one. It freezes evidence in place so that if the case goes to discovery, nobody can claim the relevant records conveniently vanished.

Sending one letter to a named defendant is routine. Sending roughly 40 of them to people who aren’t yet named defendants is a statement of intent. It suggests Apple’s lawyers believe those 40 people either hold relevant material or witnessed relevant conduct. In practical terms, it also puts pressure on OpenAI, because now dozens of its employees are personally on notice that their communications are under legal watch. That has a chilling effect on internal chatter, and it forces OpenAI to take the matter seriously at the org level rather than treating it as a two-person problem.

What does this mean for OpenAI’s hardware plans?

OpenAI’s hardware push, built around io Products and the Jony Ive partnership, is one of the most watched bets in tech right now. A wide-ranging trade-secret cloud hanging over 40 of the people building it is not a small distraction. Even if Apple never proves misappropriation in court, the litigation itself slows things down. Engineers have to be careful about what they write. Design decisions get second-guessed for legal exposure. Recruiting from Apple gets harder because every new hire becomes a potential liability.

The deeper risk for OpenAI is timeline. Hardware is brutally unforgiving. A single delayed supplier decision or a redesign to avoid legal contamination can push a launch by months. Apple knows this. Part of the strategic value of a broad legal action is not winning damages but imposing friction on a rival’s most fragile project. I’m not saying that’s the motive, but it’s an effect Apple’s lawyers surely understand.

Is Apple overreaching, or is this fair game?

Both things can be true. Employees change jobs constantly in tech, and they’re allowed to carry general skills and experience with them. The law protects that mobility. What the law doesn’t protect is walking out with specific confidential processes, documents, or supplier data and handing them to a competitor. The line between “I learned how to do hardware at Apple” and “I brought Apple’s hardware playbook to OpenAI” is exactly what this case will fight over.

My honest take is that Apple is being aggressive, and aggression cuts both ways. If Apple sends 40 letters and the evidence turns out thin, it looks like intimidation of former employees exercising a legal right to change jobs. If the evidence is real, then a 40-person net will look prescient. We don’t know yet. What we do know is that Apple decided this was worth the reputational cost of appearing to bully ex-staffers, which tells you how seriously it takes the threat.

What should you take away from this?

If you build hardware or hire from big tech, treat this as a warning shot about how seriously incumbents guard their operational knowledge. If you follow the AI race, stop reading this as a model-versus-model story. The next front in the OpenAI-versus-everyone war is a physical device, and Apple just made clear it will defend its home turf with lawyers, not just products. The company that owns the best hardware supply chain on the planet is not going to watch its people rebuild it somewhere else without a fight.

FAQ

What did Apple actually send to the 40 employees? Apple sent legal preservation letters, which are formal notices ordering the recipients to preserve documents, emails, and communications that could be relevant to its trade-secret lawsuit against OpenAI.

Are all 40 people defendants in the lawsuit? No. The original complaint named a smaller group including Tang Tan and Chang Liu. The 40 people receiving preservation letters are not all defendants, but Apple clearly believes they may hold relevant evidence.

Why does io Products matter in this story? io Products is OpenAI’s hardware venture tied to Jony Ive’s design work. The fact that Apple is targeting former hardware staff points to a fight over device-building knowledge rather than AI models.

Could this delay OpenAI’s hardware device? Possibly. Litigation forces caution, complicates recruiting from Apple, and can slow design and supplier decisions, all of which threaten a hardware timeline that is already fragile.

Is it illegal for employees to move from Apple to OpenAI? No. Employees can legally change jobs and carry general skills. What’s not allowed is taking specific confidential documents or processes, which is precisely what Apple’s suit alleges happened.
