All of the traffic leaving China goes over the CCP's network. Do you think they should be able to keep censoring the whole country? Or if Comcast started censoring municipal fiber websites, would that be okay since the traffic was going through their network?
What does any of that have to do with my private home network? I don't run a country - democratic or not, nor an ISP trying to beat out competitors. This is my network that I designed for my purposes.
Why? If it's my network, why should I not have control over all the traffic on it?
