This is not unique to Google. If you don't "vibe" with your company's culture, you are more likely to become a scapegoat. The outsiders leave or get fired, keeping the culture pure (people get fired for lack of culture fit). This mentality is indeed toxic, but the bottom line of any company benefits from harmony between all of the employees.

Not to excuse anything that's actually toxic, mind, but I think it's more subtle than that. Why is Google so inept at social media? Why are they so often blindsided by attention from regulators and tax authorities? Why Google Glass and the glassholes? Because in the pursuit of this harmony they have a limited kind of diversity based on race and gender, but they're all 20-something graduates of the same handful of universities - there's no diversity whatsoever on age or class axes. So things that are completely obvious to outsiders, they are organisationally incapable of understanding. Trapped in a local minima and unable to climb out.
