A New Future for Icanhazip

Chinese originated spam and abuse is so outrageously widespread, I don’t understand why there isn’t a conversation going on about cutting them off from the wider internet. They blocked most of it anyway.

China currently makes some absurdly large percentage of the world's consumer goods, and the discussions about producing them are probably being had over the internet. Cut them off of the internet and we have to rebuild manufacturing capacity everywhere else.

Which might not be a bad thing overall, but it's sure not gonna make any transnational corporation's bottom line happy over the next few quarters, so they'll be waving a lot of money at politicians to make this not happen.

China is an oppressive authoritarian state currently engaged in ethnic cleansing. How is enabling them indefinitely an option?

Because doing so would essentially push China towards a China-only internet, which they're already halfway towards.

The benefits of gobalization and the spread of democracy (or even just alternative governance models) via exposure to other cultures cannot be understated

Not a strong reason. I would be shocked if the average Internet user has heard of any of the top ten most visited websites in China. Their entire infrastructure, from the technological layer to the bureaucratic layer, has ensured that the average Chinese Internet user knows very little about the outside world that hasn’t been pre-vetted or filtered out completely by the GFW.
