I use DuckDuckGo for the moment but in principle I would like to switch to something that does its own indexing, I know https://www.mojeek.com/ is one such option, probably there are others.
I think both DuckDuckGo and StartPage rely on "the big ones" like Google to fetch the results from. So Google&co can decide to hide some things by simply removing those search results. In principle I would like to be able to search without any big tech company restricting what I can find.
