DuckDuckGo isn’t a browser. It’s a search engine. I really like it, and use it, but it isn’t gonna solve this problem unless you use is correctly, to search. Like I did. This isi what I got:

Regardless, I’d rather stick with something that’s limited to being a search engine than invest time in trying to defeat the information harvesting that goes on with the vast majority of “browsers”. BRAVE is decent in that regard but still suffers with some of the same issues that GOOGLE has.
