Getting from using Yandex to funding Putin‘s war requires quite a few turns. Since most of Russia’s war chest is filled by money from oil exports and China indirectly also supports Russia materially, I would first cut myself off of all oil-based products, and then from the Chinese supply chain of goods, and only then cut products indluding Yandex search results. In that order, because that matters for the war chest.

And after you then stopped typing the response, otherwise having to use a device that was made in China built from oil-based components using oil—based transport throughout its supply chain, send a postcard with your apology to the Kagi team and anyone else who does not fund wars and still uses traded goods, because this is how the world is.

If you want to throw a however tiny wrench into Putin‘s war efforts, complain load to your government to join sanctions and to have them support Ukraine and make your choice at the ballot box accordingly.

> send a postcard with your apology to the Kagi team

why? Kagi is not entitled to be paid by them, and on free market they are free to not buy a commercial product and use alternatives

and avoiding Kagi is trivial to achieve while avoiding products that were produced with oil in some way is impossible
