Tinman, your reasons for using DDG are the same ones the Post article cites:
[The developer] bet there was a place in the market for a product capitalizing on users’ emerging annoyances with Google — its search results gamed by marketers; its pages cluttered with ads; every query tracked, logged and personalized to the point of creepiness.
The article talks about DDG as "an homage the original Google — a pure search engine — and its use is soaring...."
It will be interesting to see how this plays out. At the moment, as the article points out, Google processes billions of searches per day, while DDG processes millions.
