I also switched from Google to Duck Duck Go about a week ago. It's perfect for common terms, but I still switch to Google for the more obscure stuff. But it's not like Google in 1999. Search has gotten harder, and more expensive -- which is part of why Google is doing what they can to get a competitive advantage (by hoovering up more of your data) and exploiting it (by selling the data, displaying ads based on it, etc.).
They purposely restricted that section to "personal information". If they don't tie your web history to your persona, they are free to sell it or do whatever else they want with it.
