But that's not the world we live in. Tesla posted their lawsuit online, and the details are available all over.

From the Verge, on the Zoox lawsuit:

The employees allegedly made off with information related to what Tesla calls its “WARP” system, a proprietary software platform the company built to collectively manage things like manufacturing, warehousing, inventory, distribution, and transportation. “These materials and knowhow were developed by Tesla over many years, and at great expense,” the company’s lawyers write. (WARP was described by multiple former employees to CNBC last year as “seemingly never complete,” which made it hard to keep track of budgets.)

The company claims that Turner, who was a manager at a Tesla distribution center, sent confidential documents containing information about the company’s receiving and inventory procedures, along with “internal schematics and line drawings of the physical layouts of certain Tesla warehouses” to his personal email address with the words “you sly dog you...” Turner allegedly sent another document to his personal email later that same day with a note that said: “Ooooh man... so much time and effort. Loved every second of it though,” according to Tesla.

Zoox hasn't started building anything yet. It's still in the prototype stage. It's possible that Zoox would have used this information if it got to the point of actually building a car (but see Faraday Future for an example of optimistic thinking). But Tesla would need to show that Zoox used a proprietary system for managing inventory, warehousing, etc., instead of the many platforms available on the market, most of which appear to function better than Tesla's in-house system. Tesla would alternatively need to show that Zoox used the layouts of Tesla's warehouses in designing its own.

It's the same issue that Waymo ran into with Uber: whatever the former employee may have done, the new employer isn't liable for anything if they don't actually use that misappropriated information.
