Where I work, I can make changes to what I'm working on that break things far away, from time to time. In well designed systems this doesn't happen too often, but you might be surprised sometimes how a seemingly insignificant change can make a system fail somewhere else because someone made an assumption that is no longer true.
So I can make a change, see that it breaks some test somewhere else (failed CI test), and peer into the diffs on the opposite side of the code base to decide what to do about that. It's proven quite useful, from time to time. I've seen weird problems like hitting pessimal access patterns for software developed halfway around the world.

That doesn't follow. I work on a source code repository every day, but I'd need special software to exfiltrate a copy. Same with the various design documents and things I work with—all stored in a private cloud. If I wanted to exfiltrate it I'd get a script to do it automatically.
Remember, this wasn't just the guy who started the autonomous driver project. He wasn't just the "department head". He's an industrial engineer who founded a Lidar startup. The idea that he should be denied access to Lidar design documents is patently absurd.
