Considering all the other corporate strategies Google employees have taken a public stand on lately, I wouldn't be surprised if there were serious fatigue on both ends - on corporate, for dealing with the constant rebellions killing major revenue sources (ex:- project maven's death being the end of any more government contracts); and for employees, who are likely sick of protesting an endless stream of obviously bad stuff while risking career alienation (ex:- dragonfly).

What's not immediately publicly evident is the opportunity cost vis a vis attrition and new hires - how many people have left from disillusionment? How many prospective employees are actively shunning Google directly because of these policies? (While a number might provide explicit feedback to recruiters about their reasons to reject, it's probable a silent majority is silently avoiding all contacts from Google recruiting.) At least personally speaking, I had a vastly more positive view of google around 2012 when I started grad school (more or less my dream company to work for at the time) than what I had when graduating (sufficient to decline any recruiting requests).
