I think if you were to ask “most people” about which search engine they prefer, they wouldn’t really understand the question. I remember in highschool a teacher asked someone what operating system they have at home, and she replied “I think it’s Microsoft Office”.
Tech people tend to severely overestimate non-tech peoples’ understanding of tech.
DDG isn’t the only alternative to Google. I use Kagi and love it. The results IME are definitely better than Google’s.
