I agree that greed and ignorance are playing a role here. As for the MSFT settlement, I can tell you that as a corporate defendant, it's not fun being the last defendant standing. With one one defendant to attack, I strongly believe this significantly emboldens a plaintiff and provides additional leverage. Here, with more cash from a MSFT settlement, VRNG will be in the driver's seat and may even withdraw their most recent settlement demand to GOOG.
If I was GOOG's counsel, I'd be pushing leadership very hard for a settlement now, as there are still uncertainties they can use to leverage the best settlement. Soon, however, (well, maybe soon) JJ will remove those uncertainties one-by-one, leaving GOOG with leveraging only the uncertainty of a reversal on appeal (weak leverage), and the added year before a final resolution. But with a MSFT settlement, even this added time element is weakened. Speaking of greed and ignorance (plus ego), in my strong opinion, GOOG's failure to settle before JJ's ruling will cost them over $200M. This amount is barely enough to be material where I work, but I have seen many folks terminated for significantly less.
