They were more worried about being associated with the accident than the accident itself. Lots of weasel words and excuses in trying to claim that the driver didn't work for them, or that the driver wasn't active or doing a trip.
If I worked for Uber, I would have posted something simple and left it at that e.g.
"We have been informed by law enforcement that there has been a traffic accident in San Francisco involving an Uber driver. We send our deepest condolences to the family and victims of this tragic accident."
The end.
