Yandex is not only a WEF member, but they also have an agreement with Uandex to allow Yndex browser to use Microsoft Suite - so i distrust it.
Seeing that Microsoft has a contract with Ukraine gov't, I suspect if Yandex isn't filtering results yet, they will soon. The Hated One replied to me that Yandex (email or browser, idk) is worse than Google because Russian laws differ from those in the US.
