Actually, I think for this particular case, it would have worked if these were done before the war starts.Doesn't work too well in the west anymore since the social media/host companies practice certain types of censoring post-trump/post-jan6. Also after watching every western media either bringing up "human rights" or "genocide" daily (even sports journalist) during the Olympic coverage, it is doubtful any information that is not align with the western view will get thru.
Like Douyin for tiktok, they can create a weibo for outside of China. Attract foreign users and also allow "free speech". At the very least, they have the mechanism to not censor/ban pro-china view points.
My follow contemplation is for before the war starts:
First of all, if Putin all-of-a-sudden acted like a whiny Trump and made impossible/outlandish demands for Ukraine to (only) dis-arm and dis-band the Azov battalion and arrest their unit leaders for prosecution on "nazi suspect" grounds, the western media will not try to block the news. On contrary, they will seize the story and make a huge fuss about "Putin's Real intention is actually using the Azov-problem as a pretext for war". Because this suits their interest.
The more Putin whines, they more the western media will cover it. the news idea will mostly be:
-> Putin is hiding his real intention, using Azov as a pretext for invading and annexing Ukraine. He actually wanted to invade Ukraine, war is coming!
-> Azov are Nazi-sympathizers, but so is Putin a fascist. Neo-nazism is also rampant in Russia. They are also linked with Trump and American far-right.
-> Azov are racist and antisemitic, European neo-right euro sceptics politicians like Le Pen are also nazi-sympathizers.
......
I think the western MSM will churn out the above. Because it would suit the goals and intentions of the liberal left globalists commanding the US now:
-> They want escalation of tension between Nato/EU and Russia. (War mongering)
-> They want to strengthen their general globalist left-leaning principles, at least nominally. (Thus must seize any chance to bash "Nazis" and "Fascists")
-> They want to be able to use their ideological "enemy" strawman as often as possible, in order to condition the mass audiences to think in their engineered way. This include tactics of identity politics: branding their real enemies with their memetic strawman (nazis/fascists), and even bluntly associating them together (saying that Putin, Trump, Le Pen, Eurosceptics conservatives are in bed together). Thus creating a simple division of "us-vs-them". And putting "them" altogether in the same basket.
This is how the MSM behaves. If Putin had been more social-media-dynamic savvy, he would have done those and see the MSM and social media behave in the above way.
If he did this, it might not necessarily mean that today he would be in a much different position. but it will create for him a much more un-united/divided MSM for the first 3 to 5 days of the campaign.
