I think this comment said it best:

This is an obvious, thinly-veiled advertisement for a company's services. It's widely known that ad companies track you everywhere by many mechanisms. This is why we use ad blockers of all sorts. This has nothing to do with DuckDuckGo, it's merely used as a vehicle to get clicks.

And a supplemental note from the DDG team themselves :

This title is highly misleading, implying that Google tracks DuckDuckGo searches directly, which isn’t true... please change it to be more accurate about Google analytics and other Google trackers on websites you may visit.
