Well, the Google campus is basically Software Engineer Employee Disney World. I'm sure a few of them took "The Internship" at face value and are convinced that they're doing something other than just selling ads. They can't just be elite mercenaries, that would shatter their noble, pioneering egos.

Seriously, everything Google touches that doesn't bring in ad revenue does one or both of the following:

1. Is canceled after several years regardless of quality or impact

2. Fails to change the world
