It is not Facebook’s work to make anyone smarter or aware. Maybe people should just diversify their sources of information, maybe that’s just what it is. Same way, when I was a kid, we would watch multiple news channels and read multiple newspapers, that’s what we should still do.
I dislike FB and use it as little as possible, so, generally, I’m one of the first people to criticize it for the terrible things it does. But I think people should be blamed, too, because thrusting FB as a reliable, accountable and impartial source of news — even after knowing that everything in there is customized to fit users’ comfort zone — is not only naive, it is silly.
FB has a business model that, in my view, doesn’t fit that kind of impartiality — which isn’t to say that I agree with their business model at all, but clearly it’s the opinion of the investors, not mine, that matters more to Zuckerberg. It’s up to the user to follow news-pages they thrust. If the info they are giving you turns to be of poor quality, it’s up to the user to unfollow and look for a better source of news.
That being said, me and many other people I know that were following American election from outside the country — and outside of FB — were also believing in Hillary’s victory, but with tight margins. I guess, if the extreme optimism from her base was misplaced, still the result is kinda surprising in many ways.
