I don't think this is done on purpose at the state level in Russia or China, It's just that sometimes government don't pay attention to those who do it if this is done in relation to somehow unfriendly countries. But the US also uses hacking for hostile purposes. For example, Stuxnet and some other cases. Yes, it's not ransomware, but the difference is not that huge. Western-backed countries like Ukraine are also doing the same. Anyway Just use Linux and you'll be fine for a while.
