I paid for Kagi for a bit, but got a weird vibe when I realized they were working pretty hard to paper over the fact that they pay a third party to scrape Google search results for them. The public-facing side of that coin is Kagi's position that Google should make their index available to competitors (see https://blog.kagi.com/waiting-dawn-search).
All that's to say: when I paid for Kagi, I thought I was investing in additional search infrastructure, and didn't realize Kagi had no aspirations to build their own general purpose index, and instead primarily aggregate results from other indexes, either adversarily (Google, Bing) or not (Yandex, Mojeek, Brave, Apple, etc.) I understand they do maintain their own small-web index, but I thought their aspirations were higher when I first jumped on that train.
