Your argument is not falsifiable then: If a citizen says something bad about the totalitarian government—he is true and the government is that evil; if something not that bad—he is oppressed and fearful so this is untrue and the government is that evil. I don’t mean totalitarian government isn’t evil at all, but this way of thinking would keep leading you to confusing opinions like “why hasn’t this government collapsed” or “we would be appreciated by most people if we overthrow their government” etc.
