Actually, that is significant. I studied undergraduate business and I can tell right away the difference between an MBA-run business and non-MBA-run type business. People with MBA's have a broad base of case studies, so they know how to handle some eccentric but important situations pretty well, but they tend to like formality, business plans, marketing plans instead of "screw it, let's mess around and see what happens" - not sure what the ratio of MBA to non-MBA in Google management is, but Google seems very much like a non-MBA culture. In fact, their CEO Schmidt has degrees in engineering and computer science. They probably have MBA-type people running Adwords, though, you'd almost have to.

Edit: chillingeffects.org and dataliberation.org are backed by Google, which is very much more a hacker ethos than an MBA ethos type move.

Nobody at Apple thinks it's worth the bother and loss of privacy. And I guarantee Apple isn't the only company that thinks that way.
