Blaming facebook for "breaking" democracy in the US and the UK is ridiculous. I can't understand how this can continue being a claim remotely considered valid. I agree (or may agree, at least in part) on some of the other points, but not on this.
Claiming that Trump won just because of the russians putting ads on facebook is at least naive - and ignores the fears/actual issues a very big* part of the US population experience daily. Isn't failing public schooling a problem there also? Does that give us citizen more or less prepared to actually participate in democracy?
Politicians (of all sides) in the UK have accused the EU of being the root of all evil since they "joined", again and again and again: you lost your job? Blame the EU! We can't cut taxes? Blame the EU! You really want to blame facebook and NOT the politicians themselves because people voted for brexit?
If the Russians tried to manipulate (and for sure they did, oh gosh, I'm pretty sure the US and the EU states never do - or did - anything to manipulate elections abroad! Evil Putin, why you do this to us? :cry:) we rolled out the red carpet for them!
Democracy was broken because actual journalists did not do their job. Stop doing what they (may) want you to do, using social media as a scapegoat for their own (willing, sometimes, for sure, at least if you read what Chomsky has to say) MASSIVE failure of being the "champions of truth" they claim (and blindly believe - I worked on somewhat close contact with them for years, I've seen that) to be.
