searching for "CADT" syndrome yields better results in both search engines.
As of now, the best resource (https://www.jwz.org/doc/cadt.html) is avaiable on both search engines as the first result for this query, and somewhere in the first ten or so results for "CADT Syndrome". The best set of results (for my Google history) is in Google's verbatim mode searching for "CADT syndrome" (the link under the search bar with the autocorrected version) which includes mailing lists and release notes from various opensource projects
interestingly there is also another meaning of CADT (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4610895/) which is less favored in google, but shows second place in ddg. Perhaps if we were into medicine papers this would show up higher in google.

Only ddg results include this (Hacker News) page and the comment you referenced (https://news.ycombinator.com/item?id=21337404)
Bottom line, both gave me useful results, ddg needs a better verbatim mode, google tracks me
