I prefer Kagi, which does not have ads.

But you have to pay for it and link your credit card with it. Which is privacy nightmare.

I have whatever search engine without ads for free. uBlock + NextDNS do the job.

Or chrome, or gmail, or firefox, or ... sadly most of the internet is financed by ads. Only some parts remain free of them. Wikipedia for example. And even HN here ... you can argue it is payed for by the occasional ads, or rather all of it is an ad for the VC ycombinator.

Even Wikipedia feels like each page has a prominent “Plea from Jimmy Wales” ad at the top of every page (even after donating), even if it isn’t billed as such.
