There is a conspiracy theory that recent open sourcing of Yandex tech and to some extent even a leak is a preparation for global Yandex exodus from Russia.
And so I suspect Yandex leaving it's home turf would essentially be a covert invasion of wherever they'd swarm to. Somehow, money tells me UK would be a likely target. Source: worked briefly for an exiled Russian company. Would not repeat.
> an exiled Russian company.
Either you are exhiled or you are invading, how can you be both?
Bonus "inception" points if you can make the adversary believe that you did it because they forced you to (sanctions).
I have certainly seen the kind of people you talk about, they support (or at least used to) Putin, but don't want their kids to live in Russia. I would call them more like emigrants of convenience.
