My main grief with Google is that it frequently omits keywords, contrary to DDG. As to trying to make people confuse organic results and ads, Bing is by far the worst. It often proposes malware sites when queried with open-source projects (try VLC, Audacity).
Sure having a search engine do exactly what the user requests would be great for us, IT people. Not sure it is possible to build much traffic with that alone, though.
I think DDG started doing it within last 6 months. When I just switched to it, this was not the problem. Now I am almost back to using Google, because when Google omits terms, results are a bit more on the topic (when forced not to, DDG and G work similarly).
