I used to be a part of the DuckDuckGo hype train until I found out they did actually track data (not an issue to me personally, but it betrayed their key marketing point), as used to be demonstrable if you had a slow internet and hovered your cursor over a link (it would show the tracking data loading). It was the one thing separating them from Ecosia, and I decided to join the Ecosia hype train, even if their own promises are themselves highly exaggerated. Every effort to do what Ecosia promises, even failed efforts, are appreciable.
