As far as I know, DDG does just browser/search. By extension they shouldn't be able to do as much harm as a company that provides many more services (e.g., safebrowsing/diagnostic). [edited the following 2 sentences for readability.] For example, one area possible threat could be code.google.com. DDG doesn't have a counterpart of hosted code, so it can't possibly be a threat.

Hence, my confusion. Yes, part of me was just trying to be humorously sarcastic. But part of me really enjoys some of the innovative ways that Google leverages data. And yet, another part of my thinks that they have stepped over important privacy and security lines in other areas. Hence, I prefer DDG for the vast majority of my search needs.
