I like this article’s reasoning that websites and radio stations are the same thing and therefore the government rightfully has the existing power to ban any website that it deems sufficiently Chinese.
Following this reasoning it would make sense to create a sort of digital “jumbo country-scale safety net” that makes sure Americans can only see and interact with American stuff. Doing that effectively would take a lot of technical expertise though, I wonder where we would find a talent pool for such an undertaking.
