I am inclined to agree. I've tried DDG a few times for programming stuff and the results were less satisfactory compared to Google. And actually in general, when I do searches with abstract keywords, Google gets the meaning far better than DDG.

For example, earlier today I was thinking about the mess that is USB-C standards. I decided to search for Reddit articles through the search phrase 'USB C mess site:reddit.com'.

On Google all of the first 10 results were exactly what I want. But on Duckduckgo, only the second and fifth results out of the first 10 were what I want.
