I already explained that it's perfectly common for things to seem similar or identical when they are far more different than they seem. Humans often find patterns when there are none.

And I also already explained I looked at the DDG site and I didn't happen to find that page. I did find articles on other sites mentioning that they source from Bing, but didn't really mention to what extent.

So, yes. You are absolutely being a dick by assuming I did none of that and acting the way you are. I literally only was asking for more information and explaining why.

You also left out this large piece of context which definitely makes it less straightforward that "all their results are identical enough to make them the same" as you claim

We also maintain our own crawler (DuckDuckBot) and many indexes to support our results. Of course, we have more traditional links and images in our search results too, which we largely source from Bing.
