I've been using DDG, and Ecosia. So I looked to see what was up with DDG. From what I'm reading, I'll keep using DDG.

May 12, 2023 Reuters article "No deal between DuckDuckGo and Microsoft to track users online"

"Independent experts say that DuckDuckGo blocks known tracking scripts from loading to prevent vulnerable personal identifiers from being exposed, including Microsoft-owned scripts. A separate partnership with Microsoft for advertising on DuckDuckGo’s search results page is limited to ad placements, not tracking users or building profiles, a DuckDuckGo spokesperson said."
Further, "Users sharing the headline, “Google Lite: DuckDuckGo Signs Secret Deal with Bill Gates to Track Users Online” in April 2023 can be seen (here) and (here).
The headline belonged to a story that first appeared on NewsPunch on May 25, 2022 (here), which now redirects to The People’s Voice (the two are affiliated) (here) (here).
The original article was published before DuckDuckGo eliminated, in August 2022, an exception that did permit some Microsoft-owned tracking scripts on websites to send data to Microsoft."
