You’re going to have to be more specific. There is no network-level filtering of content at the network delivery layer in the US and US can access any international hosts if the host permits it.

Search engines do have regional awareness (that can basically always be changed as a setting) to deliver more local results. I suspect this on social media platforms is what you’re referring to. It’s not exactly censorship, but they definitely promote with an agenda.

Don’t get me wrong, Trump and Republicans are fascists who deserve the worst fate and would gladly setup this kind of system, but it’s not like there’s a network component to censorship like you see in China and some other dictatorships (yet).
