Earlier quoted context omitted.
It has nothing to do with google and alphabet. Apart from being a good search engine and a competitor within the same space.
OP is describing it as an analogy of what the equivalent action by Alphabet would be and it’s pretty accurate - Yandex search remains in Moscow while the rest of Yandex operations (eg cloud) remains in the EU.
I don't believe anybody is going to pay for actual Yandex Cloud in Europe where they have AWS and Hetzner.
So even Russia-based Yandex Cloud with actual racks and users remains in Moscow. What they may keep is vague "cloud technologies" and Clickhouse. Still, these are not a large business. Think VMWare and MongoDB combined. Please correct me if you know more.
Their self-driving stuff, was also mostly used in Moscow. Genuinely hope they would find customers, such as Hyundai.
