I haven't done a deep dive into how DDG works, but "In Partnership with Yandex" is on the search results. Yandex is a Russian search engine, and while you may find the NSA snooping intrusive and obnoxious, Russia isn't exactly a privacy-respecting libertarian utopia. No one ever seems to mention the Russian connection in discussions about DDG, though. If this is something you've considered and reckoned through to it not being a concern, I would be quite interested in your reasoning.
