Honestly, I am more worried about the fact HN seems oblivious to the fact Twitter was being used as a targeted propaganda system by a foreign government than I am of censorship in the US.
A foreign government? Many governments place targeted propaganda on all sorts of platforms, the US primary among them. Both US political parties were no doubt doing astroturfing of their own this last election. And among US politicians, having corrupt foreign ties is hardly unique to Trump. Trump probably has some relationship with the Russian government, but IMO it is hardly significant in comparison to the full scope of corrupt, bad behavior exhibited by the US government.
