> it was easy to appear agnostic about search results

As Techdirt often says, this is a stupid argument. Search results, by definition are biased. You're asking Google's opinion on what is most relevant and useful. The whole purpose of search is to get biased results, otherwise you'd end up with "60 million pages containing your query 'liver'. Displaying 1 of 10, sorted number of times 'liver' is mentioned."
