>And we have seen how russian state-propaganda (in part) managed to elect a Russian-friendly president and even start a resurrection.
This narrative is one of the ones that bugged me the most, because I've seen the terrible facebook communities started by the Internet Research Agency and it consisted mostly of Broken English or content copy+pasted from English sources and like another poster said they spent an incredibly limited amount of resources. They did create some large pages but most of the posts were basically just memes with the occasional obscufated Pro-Russian thing thrown in. I really doubt this operation moved the needle in the election by even a tenth of a point.
The only thing I could have imagine actually swung the election to a Republican victory was the DNC email leaks presuming that was done by the Russians (plausible). Yet that wasn't something that could be actually be stopped with censorship given precedents like New York Times Co. v. United States, and thus isn't really relevant. What might have prevented it is more robust cybersecurity, and do people care about creating more robust cybersecurity? No, they care about implementing censorship mechanisms that will do nothing to stop the only real "propaganda" that had any influence at all.
The idea if we create centralised censorship mechanisms we will somehow free ourselves of electoral influence is just not correct given the biggest influencers and astroturfers on these platforms are advertisers whom this censorship only empowers and who have swung far more elections than just one in the United States. It bugs the crap out of me that people are more concerned with a building full of Russians speaking broken english than they are the fact that Citizens United v FEC allows magnitudes more people to work full time influencing the election for private interest than the Russians could ever dream of employing. These censorship tools will also to a large extent be under the control of the special interests that control politics and social media to begin with, which is the people bankrolling both, so you're really making issues worse more than you're solving anything.
It just doesn't make any sense, the only sense I can make about the obsession over the Internet Research Agency is that it's an embarrassing issue for Trump and Republicans. It makes Trump look unpatriotic and it makes opponents of the Democratic Party look like dupes. I mean I get the appeal. Yet I don't honestly see why anybody would actually think, man, implementing broad scale censorship on Facebook, that's what will protect democracy!
