My point is that it's called "sanctions". Calling it "cancel culture" just makes it clear you're trying to reframe Russia as some poor victim of an internet mob.
Distinction between targeted sanctions decreed by our government, and coordinated private decisions to stop doing business with any Russian. You need a word for the latter.
Let me know when you come up with that word, because the wiki page linked to doesn't describe companies not doing business with a country as "Cancel Culture".
