This is interesting. Do you consider Yandex absolutely safe to use (wrt their possible connections with the Russian government, and current war in Ukraine)?
Asking this as a geeky end-user from Estonia -- I wonder if I would be considered "suspicios" by local internet service providers, our govt/police etc if I did a lot of searching via Yandex instead of e.g. Google these days.
(For us in Estonia, I suppose "everything with possible Russian ties" seems suspicious these days, unfortunately with a reason. As a side effect, this also creates a hesitation to look into interesting projects like ReactOS, the old-dos.ru repository, etc. Russia, obviously, inhabits lots of extremely talented coders who still have the skills and mindset to push older hardware to its limits, actually still write stuff in assembly for that, use the reviving DOS distros, etc -- lots of very interesting, creative coding done there, I guess. But, I hesitate visiting their webpages due to Putin's aggression in Ukraine, them being pro-Putin, and possible spying related to all this. It's a sad state of things actually. Sort of like a loss of computer-cultural ties.)

I’d expect everything that you type into Yandex that can be of use to the Russia will be used by Russia - they will nit care about hurting you.
Just like Russia doesn’t care about online criminals being located within their borders - as long as they target outside.
While this may be true to some extent of all the countries, Russia is the one to be clearly against Estonia, Baltics and eastern europeans.
