I think many Google employees, especially those who've never worked anywhere else, treat Google like it as a university. And in the early days Google to promote this style of view. The main google buildings are clustered together and the employees treat the entire area as their own, including all the public streets which are NOT google property, which is why you see them not paying attention to stop signs or stop lights (drive extra slow if you're a visitor). They used to allow stude.. employees to work on their own projects. People bring their dogs into work. There are special after-hours clubs, themed cafes in the buildings, tubs full of breakfast cereal, goofy nap time pods, etc. It feels like a college!
Except that it's not a college, it's not a research institute, and the employees are not paying customers like students are. I think this catches some workers by surprise, especially when they get a bad grade... performance review. Then they canceled that "do your own project some of the time" and this discouraged a lot of workers. Now Google is paying big attention to the bottom line, the profits aren't just rolling in automatically, and the "resources" need to earn their keep.
