Personally I have no interest in moving away from Google Search, as I specifically use them because Google learns from previous searches I've made and shows me more relevant results. Searching "unzip" shows me the Linux command, not unrelated materials for example.
That search bubble effect is part of the reason I switched to DDG. I have no interest in being stuck in a single echo-chamber. My searches cross-over many domains and interests.
Also, the first result for unzip in DDG is winzip, followed by 7zip. It' not as ambiguous as you think, since almost nobody is curious for the general definition of a semi-common word.
Also, Google keeps me in a Canada bubble which I also dislike.
You can use StartPage.com to get Google search results in privacy. Even Edward Snowden has recommended StartPage no-logging privacy: https://www.startpage.com/eng/#home-video.
StartPage.com is also recommended by privacytools.io
It's kind of rude to advertise while giving the false impression you're a disinterested punter. It's also tiring to read the same comment plugging the same product after half a dozen posts on this page.
