It's a marketing device for people to apply to Google and become employees. Remember Google puts its employees way above its customers, and Kurian is only beginning to change that culture.
The do little work is certainly not true of everyone I know at G. Maybe some teams have slackers but in general they’ve always managed low performers out, with maybe the exception of 2020-2022 when they didn’t want to fire anyone.
Google is immensely rich from their ad business.
As long as that keeps printing money they don't really care about employees, products, development, customers or rivals.
