They're currently being investigated by the Justice Department and fired dozens of people over sexual harassment. They also maybe knowingly stole self-driving tech. Seems like a few big deals.
And those are just the bigger issues, there are numerous issues with local municipalities and also issues with driver quality (someone in my state was raped by a driver who has since fled the country) and workforce satisfaction.
There are a series of issues that will be problematic for them as they approach the need for more funding. If they aren't triaged now they're going to have bigger issues in the near future.
Honestly this is the smartest thing they've done in a while.
