Congratulations on throwing yourself into the dumpster of internet search. I appreciate your efforts to push people toward using Brave Search, Qwant, and Presearch instead of DDG's censored results. Keep "curating" yourself out of the ecosystem.
We don’t censor results. Unless legally prohibited, you should find all media outlets in our results. Related, we recently published another help page explaining how our news rankings work: https://help.duckduckgo.com/duckduckgo-help-pages/results/ne....
We do index many things (see related comment at https://news.ycombinator.com/item?id=32360874). We do not remove any results ourselves for political purposes and in fact we have been banned in China for many years for that very reason. What you're referring to was a temporary bug in our image search results from Bing that they promptly fixed. If they hadn't fixed it promptly then we would have taken further action.
Just now I went to RT.com and searched various article titles verbatim on DDG, they came up near the bottom half of results. I repeated this test with WSJ and found the link as the #1 result. From this it wouldn't be unreasonable to believe that either you or the sources you pull from are engaging in arbitrary website throttling/downranking.
I hear you when you say you don't remove content, but do you, or to what extent do you throttle/downrank websites?
