It seems as though you haven't really encountered Google process in person, you've just heard stories. Security people do have a day job, they just do security on the side because they've expressed interest/aptitude.

They don't. Google constantly runs A/B testing. Once you get it to production you've already invested the time in productionizing it.

Or that it's be far more lucrative to be acquired than continue working on Google X. You can't ascribe motives to their actions.
