I have no dog in this hunt, but I just looked this up, and there's no indication he 'resigned in protest'. Their company news site says that he resigned after being sanctioned by the EU.[0] It appears heavily implied that he was forced to resign as a result of the sanctions – either directly (I'm not familiar with how EU sanctions work) or in that it made his position untenable.

Edit: This report appears to bear out that the sanctions forced him to resign pretty-much-directly, as the company does business in Europe, and the sanctions prevent him from doing business in Europe: https://www.datacenterdynamics.com/en/news/yandex-deputy-ceo...

I was talking about the CEO Elena Bunina, not deputy CEO - https://www.haaretz.com/israel-news/tech-news/yandex-ceo-rel...

Ah, fair enough, I’m sorry - for some reason only the deputy CEO’s firing came up when I searched about the CEO, so I assumed that was what you had meant. My bad. Please disregard my comment!

No support to the fact that she resigned in protest. Please don't spread this whitewashing of Yandex. Many Russian executives stepped down so not to be hit by sanctions. She was already scheduled to be replaced by Khudaverdyan and then invasion started.

"On Sunday, an independent Russian media outlet called The Bell, which focuses on high-tech and startups, posted a screen capture of a message Bunina allegedly posted on an internal company forum. According to the post, whose veracity could not be verified, Bunina wrote: “I will not return: I cannot work in a country that is at war with its neighbors.”" - from Haaretz
