A statement from the whistleblower's attorney said Tesla had hired former members of Uber's intelligence team (that had been spying on drivers, regulators, and competitors a while back) and referenced a proposed settlement agreement for the wire tapping & corporate espionage charges that outlines the tactics (allegedly) used by Uber.[1]
It also mentions Tesla installed "specialized router equipment within its Nevada Gigafactory designed to capture employee cell phone communications and/or retrieve employee cell phone data."
Sounds like some sort of man in the middle attack? I didn't catch any similar references in the Uber document but its heavily redacted and the entirety of my knowledge in this area comes from Dinesh's criminal girlfriend so it's very possible I missed it.
