Doesn’t make much difference if it’s a western poll, the respondents are still in China (correct me if I’m wrong).

I wouldn’t trust the response from someone in Moscow being interviewed by some western news media either.

“What we are dealing with is a nonfalsifiable orthodoxy”. From Michael Parenti’s Blackshirts & Reds:

In the United States, for over a hundred years, the ruling interests tirelessly propagated anticommunism among the populace, until it became more like a religious orthodoxy than a political analysis. During the cold war, the anticommunist ideological framework could transform any data about existing communist societies into hostile evidence. If the Soviets refused to negotiate a point, they were intransigent and belligerent; if they appeared willing to make concessions, this was but a skillful ploy to put us off our guard. By opposing arms limitations, they would have demonstrated their aggressive intent; but when in fact they supported most armament treaties, it was because they were mendacious and manipulative. If the churches in the USSR were empty, this demonstrated that religion was suppressed; but if the churches were full, this meant the people were rejecting the regime’s atheistic ideology. If the workers went on strike (as happened on infrequent occasions), this was evidence of their alienation from the collectivist system; if they didn’t go on strike, this was because they were intimidated and lacked freedom. A scarcity of consumer goods demonstrated the failure of the economic system; an improvement in consumer supplies meant only that the leaders were attempting to placate a restive population and so maintain a firmer hold over them.

If communists in the United States played an important role struggling for the rights of workers, the poor, African-Americans, women, and others, this was only their guileful way of gathering support among disfranchised groups and gaining power for themselves. How one gained power by fighting for the rights of powerless groups was never explained. What we are dealing with is a nonfalsifiable orthodoxy, so assiduously marketed by the ruling interests that it affected people across the entire political spectrum.

The west is also spying on their own citizens but are obviously not repressing dissent like the three mentioned countries.

Those who do not move, do not notice their chains. — Rosa Luxemburg

Often we can say whatever we want in the West because often our voices have virtually no political power[1][2], and yet we are silenced & repressed, sometimes violently.

Just look at this very moment to those speaking out against the genocide of Palestinians that is supported by Western governments. Look at the German government’s repression and arrests, for one.

I could go on for hours with examples over the last century, including a list of assassinations by Western states of their own people for speaking out.
