Well, it costs Kagi about 1.5 cents to answer a search query. Consider how many searches you use in a month to determine how much they’re making off you at $10/mo.
I’m lucky enough to be in a position to be able to pay for products that I use, instead of relying on freemium, or ad-supported, or data-mined, or pirated products. That hasn’t always been the case for me, so I don’t judge anyone for making a different choice.
