This seems like it’s more a free press issue than free speech. Through its trade policy, the US government has restricted GitHub, a US company, from publishing certain material (the tkashin.tk website). Trade policy can reasonably apply to some of GitHub’s services, certainly, but I don’t see how a trade embargo that prevents a publisher from (virtually) printing some material passes Constitutional muster.
