Yeah, DDG uses Bing as one of it's sources. It's similar to the "meta search engines" of ye olden days.
DDG's big schtick (other than privacy) is to use lots of sources and then heavily filter the results/supplement them with additional sources (wiki, stack overflow, etc).
The founder of DDG has said he specifically wants to avoid writing a general-purpose spidering engine because you can sink millions of dollars into it and still be miles behind the competition.
