I have been using Startpage for many years (I’m surprised Adam didn’t mention it). It’s an anonymized way to use Google Search. And it’s not so much Google’s tracking that’s a problem, it’s that they use your history to “shape” search results. It’s one thing to be presumptuous about ads, quite another to be so about the search itself.
Another problem that I’ve increasingly noticed with Google (via Startpage) is censorship of results.
I’ve been using Brave Search for a few weeks now and have been impressed. By the way, it currently claims that 87% of its results globally are from its own index.
