The argument, as I've heard it, is that everyone goes to Google to find things, thus the "view" of the world is filtered by Google. If they like you, you are very visible to the world, if they don't, then you are not. So to some their very existence depends on Google returning a way to communicate with them in response to the appropriate question.

That said, while it makes it very important to an olive oil producer that they can be "found" it is less important to you and I that we find that exact olive oil producer in response to the question about where we could acquire olive oil. So Google is asymmetrically important.
