The ever-expanding operations of Uber are defined by two interlocking and zealously guarded sets of information: the things the world-dominating ride-hailing company knows about you, and the things it doesn’t want you to know about it. Both kinds of secrets have been in play in the Superior Court of California in San Francisco, as Ward Spangenberg, a former forensic investigator for Uber, has pursued a wrongful-termination lawsuit against the company.
 
 The case, filed in May of last year, has weaponized Uber’s secrecy. Most sensationally, Spangenberg’s suit got significant press coverage in December for his claims that company employees accessed its data inappropriately to track exes and to spy on celebrities like Beyoncé. Uber responded to those claims by saying that employees only have access to the amount of customer data they need to do their jobs and that all data access is logged and routinely audited, with thorough investigations performed in the event of potential violations.
