This really isn't all that different than what is happening elsewhere across the world today. Your Uber rider score represents your "social credit" for that service. Your Airbnb guest reviews impact if you will be allowed to rent a room. Each platform is putting social credit in place via crowd-sourced "trust"
EDIT: I don't mean to minimize China's human rights violations, but to posture that independently of central control many companies are implementing their own versions of these systems, which can have _some_ of the same effects in terms of losing access to services. Obviously one's Uber scores won't put you in jail / detainment camp and I was not intended to imply such.
