So here’s a scene for you. It’s an engineer’s last day at Apple. His phone keeps buzzing. “I found a 64GB drive,” he texts an old coworker. “Do you think that will work?” A minute later: “I think 200 ish. We start from 64. Better than nothing.”
Weird thing to be reading, right? Except this isn’t fiction — it’s a real text message, pulled straight from a federal court filing, and it’s now sitting at the center of one of the nastiest tech feuds in recent memory. Apple says OpenAI built its shiny new hardware team on stolen Apple secrets. OpenAI says, essentially, nice try — and then went ahead and posted a pile of private emails and texts online to make its case in public. There’s a $6.5 billion acquisition tangled up in this, a genuinely funny case of mistaken identity, and a lawsuit that honestly reads more like a screenplay than a legal brief. Let’s untangle it.
How We Got Here
On July 10, 2026, Apple walked into federal court in California and sued OpenAI. Not just OpenAI — also its hardware arm, io Products, plus two people who used to draw a paycheck from Apple: Tang Tan and Chang Liu.
Those two names carry a lot of weight in this story, so let’s get them straight.
Tang Tan put in nearly a quarter century at Apple, eventually running product design for the iPhone, the Apple Watch, and AirPods. That’s about as senior as it gets on the hardware side of that company. He left in 2024, and today he’s OpenAI’s Chief Hardware Officer — the guy steering whatever gadget OpenAI is cooking up next.
Chang Liu spent eight years as an Apple engineer. His last day was January 22, 2026. He landed at OpenAI not long after — and, as we’ll get to, that timing turns out to matter a lot.
And then there’s a name that isn’t technically on the lawsuit but that you can’t really talk about this case without mentioning: Jony Ive. The guy who designed the iPhone left Apple years back and started his own hardware company, io, with Tan as a co-founder. OpenAI eventually bought io for a reported $6.5 billion. Ive somehow avoided getting named as a defendant here, but nobody reading this complaint thinks he’s beside the point.
And Apple isn’t just upset about two guys — the lawsuit claims more than 400 former Apple employees now work at OpenAI. Apple’s whole argument is that this isn’t some coincidence of the labor market. It’s a strategy. Build a recruiting pipeline out of people who already know where Apple keeps its good stuff.
What Apple Says Actually Happened
Read the complaint and it stops feeling like a business dispute pretty quick. It reads more like a spy movie treatment. A few of the highlights:
- The laptop that never came back. Apple says Chang Liu kept his work laptop after leaving and used it to pull down more than 1,000 pages of confidential material — unreleased product plans, engineering decks, technical specs, all of it.
- Bring your Apple parts to the job interview. Apple claims Tang Tan told candidates who were still working at Apple to bring actual hardware components to their OpenAI interviews, supposedly for “show and tell” sessions that conveniently doubled as intel-gathering.
- A how-to guide for sneaking out. The suit alleges OpenAI coached departing Apple staff on dodging Apple’s exit security checks.
- A bug, allegedly put to use. One part of the complaint describes an employee finding a security flaw and a colleague offering to help exploit it — texting “I’m ready” before pitching in on grabbing more files.
- Not a few bad apples — the whole orchard. This is really the heart of Apple’s case: it’s not blaming a couple of rogue hires. It’s arguing this behavior was tolerated, maybe even encouraged, from the top.
Legally, Apple is going after two things: breach of the confidentiality agreement every departing employee signs on the way out, and violation of the federal Defend Trade Secrets Act. No consumer angle here — this is strictly Apple versus these specific defendants, and Apple wants both money and a court order.
One detail that’s easy to skip past: this lawsuit landed not long after reports that OpenAI itself had been considering suing Apple, over how ChatGPT got wired into Siri. Apple insists that’s an unrelated matter. Maybe. But it’s hard to read that timing and not think these two companies had already been circling each other for a while.
Then Apple Asked the Court to Hit the Brakes — Now
A lawsuit, apparently, wasn’t urgent enough. Apple also filed for a preliminary injunction, which is basically legal shorthand for “we can’t wait for a trial, stop this today.” The ask: block OpenAI and the two former employees from touching, using, or sharing anything Apple considers a trade secret while the case works through the system, and make sure nobody destroys evidence in the meantime.
Here’s the detail that actually tells you something. After filing suit, Apple offered OpenAI a deal — agree to five conditions, and Apple would back off the injunction push. OpenAI said yes to three of them: no future access to Apple’s information, cut off whatever access currently exists, and preserve evidence. But it said no to the fourth — letting Apple’s lawyers and outside forensic investigators loose on OpenAI’s own devices, storage, and accounts. That one refusal is basically why a judge is now involved.
OpenAI Skips the Courtroom and Writes a Blog Post Instead
Usually, when a company gets sued, its lawyers do the talking and everyone else stays quiet. OpenAI didn’t play it that way. On August 3, it published a blog post — no byline, just posted under “OpenAI” — with a title that doesn’t leave much room for interpretation: “Apple is getting this wrong.” And it didn’t stop at strongly worded paragraphs. It published the actual emails and text messages.
“Apple is one of the greatest companies of all time, and built a reputation for obsessing over the smallest details. This careless, aggressive and oddly personal lawsuit sadly doesn’t live up to that reputation.”
From there, OpenAI lays out four main counterpoints — and backs up most of them with receipts.
1. The email that went to the wrong guy
Apple’s version of events: it reached out back in February and OpenAI just ignored it. OpenAI’s version: not quite. According to the emails it published, Apple’s outside lawyer, Gabriel Gross, sent a letter to OpenAI’s General Counsel, Che Chang, on February 23. A few minutes later, Gross fired off a second email that was actually meant for someone else entirely — apparently he mixed up two people with similar-sounding last names.
Che Chang’s actual reply, which OpenAI shared in full, does not hold back: “This guy from Weil claims to be representing you… he is lying about speaking with me on the phone. I don’t know who he is and we have never spoken.”
Apple’s own lawyers later admitted the mix-up. But OpenAI’s real point is what happened after that — nothing. Apple never followed up on the specific claims that eventually ended up in the lawsuit. It just said it was “resolving any issues” and then went dark. For five months. Until it sued.
2. The text messages nobody saw coming
This is the part everyone’s actually talking about. OpenAI released redacted iMessage threads between Chang Liu and his former Apple coworkers, running from his last day into early March. And the texts tell a strange story — it wasn’t Liu chasing after Apple’s secrets. It was Apple’s own people messaging him, asking for help finding files, even keeping his iCloud account logged into a work laptop so they could pull material off it.
At one point a coworker mentions leaving Liu’s iCloud connected. Liu tells him to sign out, half-joking that “there might be my new company stuff showing up in that laptop.” Later, when a work thread starts pulling him into internal Apple discussions he clearly shouldn’t be part of anymore, he pushes back: “this is highly irregular, please remove me from this thread.”
OpenAI’s interpretation: none of this was Liu breaking into anything. It was what the company calls “residual access” — Apple failing to properly shut off a former employee’s accounts on the way out, which OpenAI says happens more than Apple would probably like to admit.
3. Standing up for Tang Tan
On the claim that Tan pressured job candidates into leaking Apple’s secrets, OpenAI doesn’t publish any documents at all — it just vouches for him. He’s always told his team not to touch other companies’ confidential information, the post says, and points to 24 years of good standing at Apple as the character reference.
4. Calling the injunction request unnecessary
OpenAI closes with a fairly blunt line: the request for an emergency order is “based on false information and completely unnecessary,” because, as it puts it, “we do not have, nor want, any of their trade secrets.”
Smart Legal Strategy, or Just Loud?
Not everyone’s convinced the blog post actually helps OpenAI’s case in court. John Gruber, who’s covered Apple for years over at Daring Fireball, pointed out that Apple’s injunction filing includes a sworn statement from a digital forensics expert — laying out, in real detail even with redactions, how Liu allegedly accessed Apple’s files. His read, echoed by Dan Moren over at Six Colors, was that OpenAI’s post feels less like a rebuttal of that evidence and more like table-pounding. You know the old saying — if you’ve got the facts, argue the facts; if you’ve got the law, argue the law; if you’ve got neither, you pound the table.
There’s also a subtle shift worth noticing if you’re paying close attention. Back in July, OpenAI’s language was careful — just “no interest” in Apple’s secrets. By August, that had hardened into a flat denial: it doesn’t have them, period. That’s a much bigger claim to put in writing, and it’s exactly the kind of statement that gets stress-tested hard once real discovery starts.
Why Anyone Outside These Two Companies Should Care
Strip away all the drama and this is really a fight over who owns the next big product category. OpenAI’s hardware team — Ive and Tan running the show — is reportedly working on consumer devices, with rumors floating around everything from a smart speaker to a phone that might not even land until 2028. Apple has owned consumer hardware for two decades straight. It’s not about to watch that turf get contested without putting up a fight.
If a judge sides with Apple on the injunction, OpenAI’s hardware plans could stall out at a genuinely inconvenient moment. And no matter how the case ends, Apple’s already sent a message to its own people: think twice before your new employer starts looking suspiciously like your old one.
Where This Goes From Here
A judge still has to actually rule on the injunction request, and if we’re being honest, this feels like the opening chapter, not the finale. Expect more filings, more evidence to surface, and — given how public this has already gotten — probably a few more blog posts before anyone can call this settled.
Worth repeating: everything in Apple’s lawsuit is still just an allegation. No court has ruled, and nobody’s been found liable of anything. OpenAI’s blog post is its own version of events, not a legal finding either.
Frequently Asked Questions
Okay but — did OpenAI actually steal Apple’s secrets?
Honestly, nobody outside the courtroom knows yet. Apple says yes, and has a sworn statement from a forensics expert to back it up. OpenAI says no, and published its own emails and texts as a counter. Right now it’s genuinely one company’s word against the other’s, and no judge has ruled on anything.
Remind me who Tang Tan and Chang Liu are?
Tang Tan ran product design for the iPhone and Apple Watch at Apple for over two decades, and now leads OpenAI’s hardware team. Chang Liu was an Apple engineer for eight years before joining OpenAI in early 2026.
Wait, is Jony Ive getting sued too?
Nope. He’s not named as a defendant, even though he co-founded io — the hardware startup OpenAI bought for roughly $6.5 billion — alongside Tang Tan. He’s all over the backstory, just not on the actual court filing.
What is a preliminary injunction, in plain terms?
Think of it as an emergency brake — a court order that can kick in before the underlying lawsuit is even decided. Apple wants one that would immediately stop OpenAI and the two former employees from touching or sharing anything Apple considers a trade secret while the rest of the case plays out.
If OpenAI has nothing to hide, why not just let Apple check its computers?
That’s basically the question skeptics keep asking. OpenAI agreed to several of Apple’s other conditions but drew a hard line at letting outside forensic investigators loose on its internal systems, arguing the request is unnecessary since it says it never had Apple’s data in the first place. Whether a judge buys that reasoning is still an open question.
What’s OpenAI’s strongest argument here?
Probably the text messages — they suggest Apple’s own employees were the ones reaching out to Liu, not the other way around, which really complicates Apple’s version of events. The February email mix-up is a good process point too, but it doesn’t touch the core theft allegations the way the texts do.
Why does a dispute over two employees matter this much?
Because underneath it, this is really a proxy fight over the next big consumer product category. OpenAI is reportedly building its own hardware — a smart speaker, maybe eventually a phone — walking straight into territory Apple has owned for two decades. Both companies have a lot riding on who gets there first, and cleanest.
So when do we actually find out who’s right?
Not soon. A judge has to rule on the injunction first, and that’s really just the appetizer — the full case could take months, possibly years, working through evidence gathering, depositions, and potentially a trial.
