Ecosia is based in the EU and it's working together with Qwant to build an European index. But Ecosia's mission is planting trees, and in order to do that they need revenue, which comes from targeted advertising.
I want to support an EU company and the eco mission, but I also want privacy. I used to use Brave but I want to move away from that and still avoid leaking my data to Google.
I think the difference between "targeted" and "contextual" is an important one to make re: privacy. "Targeted" means they're tracking you and using your characteristics to customize the ads; "contextual" means they're just showing ads related to the search term.
