This title is highly misleading, implying that Google tracks DuckDuckGo searches directly, which isn’t true. It also reinforces a conspiracy theory that we’re owned by Google, which also of course isn’t true. Kindly please change it to be more accurate about Google analytics and other Google trackers on websites you may visit. We’ve been sounding the alarm about Google analytics, tag manager, and other Google tracker…
Furthermore, I don't see any intimation in the article that Google owns DuckDuckGo.
All in all, it seems you and the article are on the same page.
