"DuckDuckGo's ties to Yahoo are seriously unhealthy (do a search) and the results aren't as good either. Startpage is decent or even try Qwant or something else..."
Which will all just get taken over eventually. Because without the ad revenues, how do the search engines stay in the black? Essentially, they can't. Privacy costs but no one's willing to pay for it these days. Frankly, not too many people even care about their privacy (not even down there--consider flashers and streakers).
