Well, there is more than one social allegory related to Moloch. Many of them have no obvious relationship to Google. Which is why I asked the question in the first place. So people tried to be helpful and identify any sources that might be related.

I just read the character description for Moloch in Paradise Lost, and don't see any obvious theme you might tie to Google.

In fact, I'm still not quite sure what the original comment was trying to say. Apart from some fuzzy notion that capitalism is sort of like Moloch and we keep feeding it with our "children". Where children is what? Privacy? Money? Open source tools?
