Of course they do, when the alternative is Google.

Do you want to try and argue that Google is a more private search engine than DDG outside of the US?

privacy isn't the only one criterion to choose search engine. If search quality is very poor for a language, it's not suitable even if it's privacy oriented.

Sure, but that's really a separate conversation than what this thread has been talking about so far -- which is whether or not we can trust that DDG is more private than Google.
