Okay, sure. I agree that this is an unfair advantage. But like, I've been using DuckDuckGo for a while and the best thing about it is the ability to easily search other search engines. Their own actual search engine isn't exactly great.
Mostly using it makes me realize how much time Google saves me by already having my location and search history. I still don't trust them and it isn't what it was a few years ago, but it's the actual quality of their search that's keeping them on top.
Also like, why does clicking a thumbnail in video search not take me to the video? Dumb.
