All I know is, I have done nothing myself to PRC China, yet my basic linux and BSD setups are daily refusing all kinds of stupid and smart hack attacks via the Internet from that address range.
eg. I set up a new domain a few days ago & within a short period of time, the first two IP's to run sniffers on it were US based (Arizona and Illinois, IIRC).
eg. A server I set up a few months back was getting hammered on an alternate SSH port, primarily by US servers. (Admittedly, there was a mis-configuration on my part which had the port responding to anyone but me in the first place)
Pot. Kettle. Black.
As time progresses, the ongoing war of of 'openness' vs 'sovereign rights' when it comes to the internet has only escalated, and will obviously continue.
Mr Trump's decision has clearly favoured the Chinese method of 'sovereign rights': countries and regional zones will be increasingly demanding dominance of their feifdom (such as GDPR vs Chinese wall vs Australian AAA "Assistance & Access Act" vs California's CCPA).
How should tech respond? It's either the web should be un-splittable, or infinitely splittable. We all know it's 'self healing'... but only to the limit that state level access allows it.
Some would say the easiest solution would be a de-escalation of the network centralisation that the web has: AWS, GC, Cloudflare, FB, Twitter. But, the (ironic) concept of "federation" that exists (Mastodon, NextCloud), only makes a single server cluster easier to be sliced off.
Either way, a single voice can be cut off by state level/mega corporate, whether it be a centralised system or federated, far too easily.
That even Mr Trump is getting tweets and FB posts 'moderated' is a sign that centralisation by corporations is definitely a problem.
