I doubt the story of the bots disappearing, but Yandex a) has specifically given control to Russian government, by providing a super-share that doesn't pay dividends but gives the deciding vote, to Sberbank (this kind of share shenanigans are possible under Netherlands' law, where Yandex is incorporated for this very reason); and b) does provide cloud-hosting services the same way as Amazon does. Yandex is generally considered to basically be a government corporation by now, it's one of like three candidates whenever the government decides to introduce some ‘sovereign’ service like Russian analogue of YouTube.

Arkady Volozh, the surviving cofounder of Yandex, has left Russia over disagreements about the war and the government's control, taking for himself some side business that Yandex was doing abroad, either drones or self-driving cars or something like that. And relocated some 1000 Yandex employees that decided to leave with him.
