Yandex is arguably the biggest censoring and propaganda machine in Russia.

Yandex News is IIRC the biggest news media in Russia.

It filtered all results on protests and opposition resources leaving only government propaganda. Same with war. Filtering not meaning downranking. Just straight up not showing.

Editors were fired for not staying in line until it was completely sterilized and filled with pro-war propaganda.

Working in Yandex is being complicit with it.
