Thy was what, 40 years ago? China has their great firewall set up today, never mind their social credit systems, automated CCTV citizen tracking systems, etc. Russia has people accidentally falling out of hospital windows or drinking polonium tea. I don't think this is at all comparable.
I checked Wikipedia to learn about the Social Credit System, and according to the article, no such system exists as described. Most assumptions about it seem to be based on misinformation from Western media. Could you clarify what you mean?
