I did the same as soon as I heard it was an option. 👍
For those who may have only a partial picture, it is my understanding that:
1) Main #DuckDuckGo is Bing (Microsoft) under the covers, with the #surveillance bits removed. This is a good start IMO.
2) For some reason, DDG feels compelled to promote its version of "#AI Assistance". You can politely refuse, but as soon as you delete cookies the promotions return. They also have support for "good ads" (which I also politely refuse, and then they return unbidden). Both features should be "opt-in" and not on by default! 🙄
3) The "noai." prefix yields the same DDG with all the AI cruft removed (https://noai.duckduckgo.com). 🙂
Anyone have better information than the above?
