Uber's wrong turn

Uber CEO Travis Kalanick has resigned from the ride-sharing service he co-founded, another twist in a rough year for the company. Uber has faced scandals on multiple fronts. The company launched two investigations into allegations of harassment. Kalanick, who took an indefinite leave of absence last week, was at the center of controversy over a profanity-laced outburst with an Uber driver that was caught on video. There's also a court battle stemming from allegations that Uber stole trade secrets from Waymo, Alphabet's (GOOGL) self-driving car development company.
