> Aren't your Kagi searches tied to a payment method? Kagi accepts Bitcoin [1]. They also “do not log searches or in any way tie them to an account” [2]. [1] https://help.kagi.com/kagi/plans/payment-methods.html [2] https://help.kagi.com/kagi/privacy/privacy-protection.html
They also “do not log searches or in any way tie them to an account”. So you essentially have to make the same leap of faith as you would with a commercial VPN.
With a VPN you're hoping there's no logs at all, and it's pretty easy for a VPN vendor - entirely by accident - to keep some logs around. And then a search warrant lands, they look around, find the logs, and the promise is broken. And it's entirely possible for that to happen by accident. So if I pay for a commercial VPN that claims they don't keep logs, I'm gambling on their honesty and competency.
With a search engine you're hoping they don't bias search results to favour advertisers, sell your search results to advertisers, etc. And that's not something you can really do by accident. If Kagi is being honest, then they're not accepting money to modify search results, nor are they logging my searches, or building up a profile of my searches, or modifying seearch results based on that profile, etc. Even if it turned out Kagi goofed and really were logging all my searches and tying them to my payment account (maybe, eg, for perfectly innnocent reasons, like solving a bug), that doesn't actually change their value proposition to me all. They're either super evil and lying about everything they're doing, or they're fine, even if it turns out they're cutting a couple of corners.
Kagi is putting themselves in a position which is inherently easier to trust than a VPN vendor (or early Google), due to the nature of the business model.
