The Waymo lawsuit is still very much up in the air. Kalanick's involvement is already public: he collaborated with Levandowski to acquire a team of self-driving-car engineers and their work over 8 months. The key demands of the Waymo legal team were rejected in their injunction. Judge Alsop did not see a clear nexus between the Waymo designs and the Uber lidar, referring the matter to trial.
Based on what? Uber isn't public, they aren't forced to release any information on their ride sharing, and what info they do release isn't subjected to any real verification.
The only article I see is based on "number of app downloads" - that has literally no relevance in the number of rides they're servicing. I've got Uber on my phone and I haven't used it in 3 months and I don't see that changing anytime soon. They didn't lose me outright as a user, but they, for all intents and purposes, lost my business.
