DuckDuckGo: No, we’re not using browser fingerprinting to track you January 7, 2019 https://techcrunch.com/2019/01/07/duckduckgo-browser-fingerprinting/
The search engine may not track, but sites still do in many forms, what the point of a non-tracking search engines if they orient you to those tracking sites. If DDG only list non-tracking sites, it would be great but I guess they will be out-of-business.
