It also, consequently, makes the advertisements which they show to you *far* less valuable. So this feature is not widely advertised.

I do wonder how much more effective surveillance capitalism-style ads are compared to ads like what DuckDuckGo has that are based on what you’re searching for right now. I’d personally be more likely to click on an ad based on my current search where it’s directly obvious how they know my interest, as opposed to seeing a creepy ad on a random website where they magically know I recently considered buying new shoes.
