If you do a search for the same terms in DDG vs Bing, you'll find that the results are very similar. DDG lets Microsoft do the dirty work of abusively tracking users to max out on ranking factors, and then DDG reaps the benefit. DDG doesn't need to get its hands dirty, because someone else is doing so much of that for them.
By leaning so heavily on Bing, DDG is a blood diamond merchant of privacy. They might not own the mines or directly command the labor, however they're quite happy to buy the blood diamonds to further their own profit afterward. And DDG's users go along with the scheme, because buying into the con helps them sleep better at night. It works like this mentally: those users over there (at Bing) are having their human right to privacy violated, I know it's going on, and I directly benefit from the search data training as I use DDG, but hey at least it's not me being abused, so I can do my virtue signal dance and sleep well at night comfortable in my compartmentalization.
