If you scroll down the list of reviews here you will notice that the reviews with 1 and 2 stars have the most votes for being helpful. A blind man can see this is a deliberate attack in an attempt to discredit the DuckDuckGo search engine.
This is a free service that does not play the privacy violation games that google does. Also, google is politically liberal in its search results when using it for searching about politicians. I am so sick of the Internet telling me who to vote for. So far I do not find DuckDuckGo doing this.
