Kagi uses Russian search engine Yandex (EDIT: among several other sources) to produce search results, which means they pay them, which means indirectly sponsoring Russia's invasion of Ukraine.
There are more or less valid arguments for not excluding Yandex[1], but as a European, I want to avoid any of my money going to Russia if possible. And there is no setting to exclude Yandex from your Kagi search results.
If you stopped using duckduckgo because of the tankman fiasco, maybe you should reconsider if Kagi is right for you.
