Jeff Jones, president of the embattled ride-hailing company Uber, has resigned just six months after taking the job, the company confirmed Sunday. In a brief statement, Uber didn't say why Jones left. "We want to thank Jeff for his six months at the company and wish him all the best," it said. Jones told the tech blog Recode, which first reported his resignation, that his values didn't align with Uber's. "The beliefs and approach to leadership that have guided my career are inconsistent with what I saw and experienced at Uber, and I can no longer continue as president of the ride sharing business," he said in a statement.

Waymo, a self-driving car company that used to be part of Google, last month sued Uber in federal court, alleging betrayal and high-tech espionage. The complaint accuses Anthony Levandowski, a former top manager for Google's self-driving car project, of stealing technology now propelling Uber's effort to build an autonomous vehicle fleet.
