Here is some context for those who aren't current on the case.
One result of the injunction (all of the hearings up until now) was that uber needs to use all of its power to compel levandowski to testify, the extreme limit of which is firing him. Uber followed through as was legally required
This is one part of a number of things that came out of preliminary injunction hearings, other parts are (1) the breadth of the case is much smaller than as originally filed, its now about trade secrets, not about patent infringement (2) Waymo is allowed a bit more indepth "discover" to see if they can find evidence of their tech in ubers documents or in ubers hardware itself.
Legally, there is no inference that can be drawn from this to imply uber is guilty, they have willfully carried out a court order.
Uber still has a self driving car program, that is staffed by a few hundred engineers.
The case against levandowski has been referred to a federal prosecutor to review the possiblity of criminal charges against levandowski, if I was his lawyer and he was in this position, I would likely refer him to "plead the fifth" regardless of his guilt.
The case is most definitely still going to trial
