That doesnt make much sense to me. Google's interests are not microsoft's or DDG's interests and to hold up Google as some sort of ground truth in what the optimal search results for a given query are is, as proven by Kagi, highly deluded and also quite subjective.

If true however, it does go to show that Google is really a monopolist in the search space as well... and to substantiate this claim would go a long way into proving that.
