I been using DDG for a couple of years now and while a anecdote I can assure you: the data they sell can easily be correlated by tracking companies. It’s just a matterr of having the full picture or not. But if your behavior is the same it’s easily correlatable. Also I don’t trust their onion website. Besides all your searches is going to Microsoft(Bing).

This article was “it” for me. No more DGG for me.

I just want to point out the reason torproject does not ship Tor Browser with adblockers is not only technical(fingerprinting) but financial.

I can’t find it right now but the Tor Project was saying that orgs would not donate if they shipped with adblockers like ubo.
