It does have the feel of a TV show at this point. Given @sarahjeong's coverage on Twitter and in the Verge I would not be surprised if Waymo's legal team felt they were going to at least not win, and might lose.
And to my thinking Waymo had lots more to lose than Uber did. (and I think that is reflected in the settlement being not quite 13% of what they were asking, and in stock which may be completely worthless). Waymo loses and it might embolden other Google employees to go to competitors, it might embolden those competitors to try to recruit their top engineers to bring their ideas into the competitor. It might completely blunt Googles ability to get any engineer to believe what the company thinks of as trade secrets would actually be considered trade secrets in a court and so they aren't as threatening as before. And on cross examination Uber might have pulled some things into open court and the public record that Waymo would rather not have out there.
Uber on the other hand already has a reputation as being a rule breaker, and skating over the line. So what do they have to lose? I Waymo can take $1.9 billion in cash out of Uber (maybe more if they can get lawyers fees etc) they can take them off the board completely.
According to the coverage they were being berated by the judge and their case had gone from being about patents to about trade secrets to about 8 trade secrets. That is not a legal case gaining steam, that is one that is trying to stay alive.
