The only major color on the page is the red navbar and the yellow sponsored ad. The sponsored ad draws my attention and then I go below it since it's an ad.
The zero click info and official site badge are both grey which makes them fade away into the background; not stand out like intended.
Given DDG's relatively ad-blind early-adopter audience, I reckon the sponsored link would get more attention if it wasn't highlighted in yellow
(I don't think this is a "dark pattern" when the text "sponsored link" appears next to it - alternatively the sponsored status could be clearly but not obtrusively indicated with a badge similar to the "official site" badge)
