Put this invasion into perspective. It is basically akin to the Soviet-Afghan War. There remained journalistic exchange and diplomatic exchange even at the height of the Cold War when US/USSR were fighting each other by proxy on simultaneous fronts.
Personally, I want the Russian perspective as well as the Ukrainian perspective and the Western perspective and the rest of the world's perspective, too. I can understand arguments against it, but despite legitimate concerns it's not something I'm going to agree with. If the Russians were an actual, immediate, threat (war-threat) to us, I would agree. They're not, though. The only threat here is a potential nuclear war because if it goes hot then it will go nuclear as a matter of fact and all the propaganda won't matter a bit. Also, the people who swallow Russian propaganda are the same people you should be convincing of its absurdity (by pointing out the absurdity of our own propaganda, too). And these people will find a way to get that content somewhere else. All you're doing is pushing them further into individualistc silos.
If we're going to be told about Russian media by Western media, then the first thing I'm going to do is go straight to Russian media because of a healthy distrust of Western media (cultivated over a lifetime and based in their outright lies and manipulative tactics). One set of half-truths against another with the two being weighed by the self-interest of different ruling classes in different states (or different states if you don't buy the class line). It just means I have to read against the grain of Pravda instead of RT. And if that goes, then some other Russian outlet.
Just on the covid thing. That was mostly Western people in my experience. Not saying Russians might not have tried to push it, but there was enormous vaccine hesitancy in Russia, too. And social media was the biggest problem there, not Russian media (the conspiracies you saw predated Russian broadcast establishments in many cases including anti-Semitic theories). Also, the US has to be the greatest exporter of conspiracy theories in modern history (well before Russia).
