Public services, especially those run by China, don't exactly have a stellar record of being uncorrupt and accountable. What if the system is abused to shut down a competitor on the surreptitious "donation" of another company? What if being LGBT or the wrong religion is made demerit-worthy?

It would bother me a lot less if it were private and governed private services only. There's more accountability in the sense that, there will always be services available that don't require the credit system, and there will be multiple competing bureaus ala the current credit system.
