Re: "they would feel similarly about Russian kit."
I feel a bit sorry for Yandex here.
For all its faults (and, yes, there were many), the USSR invested a lot (and Russia still does) in STEM education, and there are a lot of smart STEM people there. Russia (as does the rest of the world) deserves to have successful businesses and a strong economy, benefiting the whole population (and not just a few dodgy oligarchs and the like).
But, sadly, as we all know, it didn't quite work out that way, and the actions of the Putin government have long been deplorable, not just regarding Ukraine, but in many other ways too. It would be nice to hope that one day, hopefully fairly soon, Russia gets a better leader and government and it can start to have some proper successful businesses (and not just dirty fossil fuels) and improve everyone's standard of living.
Yandex could perhaps become one of those, but the awkward thing is that for historical and current reasons there will still be that fear in the west that they might be heavily leant on so that echoes of Soviet-style literal spyware might be in their code (not that many US internet services can claim the moral high ground there). Maybe in time that may no longer be a concern, but I suspect it would take substantial changes in Russian politics and probably at least a further generation…?
