In my experience at Google it was clear that in Mountain View there was a program of 'managing out of the company' people who created problems. The sorts of problems they sought to minimize were disagreement or discussion that made actionable criticisms of management decisions.
As much as I dislike the actions of James Damore, his case, if it proceeds[1], has the potential to put a lot of this activity on the part of leadership into the public record. I personally think they will figure out what it will cost to buy his silence and make the case go away which won't serve the interests of the current employees.
