Corporations like Google certainly encourage a focus on in-group relationships between employees to reduce churn (i.e. increase stakes for disgruntled employees who might consider quitting). The entire idea of having scheduled leisure activities, daycare, laundry services, etc all provided either by the company or facilitated through the company encapsulates current employees and gently excludes former employees, which likely helps reduce their ability to spread or air negative sentiments following their departure (which apparently can be fairly rapid, which also means fired employees will be stunned and possibly in shock for the limited duration where they may still have access to other employees directly).

There's a reason the "employee retention" behavior of companies like Google and Facebook during the web 2.0 craze was often compared to actual cults.
