I read the article, the "Sesame Credit Score" is tied to social media accounts, not people. If the chinese use different social media accounts to purchase goods and to express political views, there are no ties. Problem solved.
Bitcoin adoption is not driven by china. I believe they don't actually use bitcoin. Their trading volume is exaggerated and some buy bitcoin to transfer out of china. The "Sesame Credit Score" is not going to have any effect on global adoption.
