See that’s the thing: the fact that the west lies doesn’t mean that the east tells the truth. You are heavily skeptical of what the west has to say (good) but mostly uncritical of what any communist government has to say (bad).
Capitalist countries have done horrible things, but so have self-proclaimed communist countries
I have entire history books about how the west lies.
There is not a similar body of data about the loss of the east. Is it perfect? No. Do we have any reason to belive they are as bad or bad in the same kind of way as the people who oppose them? No.
General note: Most authors publishing critical material of the west in the (free speech) west don’t get silenced (edit: although professional blacklisting is all too common). Yes, I’m sure there are exceptions. You might not want to do that openly in China, Iran, or Russia these days, because the risks are well known/accepted. It definitely makes life harder for scholars and historians.
Do you have any evidence of China suppressing criticism? We know the western media openly brags about making up stories about the east.
I can find plenty of stories of publishing houses declining to publish material. That is effectively censorship but because it is done by a company we don’t care
Russia and Iran are more like the US than China so considering them as one unit is not helpful.
