Ran across an article that points out nearly all search engines are Google based.
Bing is its own creature and DDG is Bing based as well is Yahoo.
There is a Russian search engine Yandex.com that is different from Bing and Google.
So maybe a combo of using Google, Bing and Yandex will help you avoid only seeing curated results from one perspective.
Not that I trust Google, Microsoft or the Ruskies
