That's utter nonsense, and actually echos one of the propaganda lines that an actual totalitarian regime uses to deflect criticism of its actual oppressive polices. You're also forgetting that lots of people buy into totalitarian government propaganda, and push it voluntarily (from stuff like this https://www.nytimes.com/2019/01/02/business/china-internet-c... to nationalist internet trolls to Red Guards).
Real totalitarian regimes do stuff like this (https://www.nytimes.com/2021/02/26/business/china-online-cen...) and worse. Your so-called "worse" regime just occasionally has bosses fire employees for saying something impolitic and business that refuse to carry certain items (with the effect of only making them slightly harder to buy).
