Fake News isn’t the problem. The problem is that we expect to be spoon-fed the “correct” information, and have become incredibly lazy at thinking.
Facebook has been lambasted following the US election. Facebook is an entertainment site which surrounds you with friends and people who think similarly to you. It is a vehicle for delivering information, but tends to deliver to an individual information from those friends etc. If you rely on it or any other single platform to tell you how to speak, think, act, or vote, that is your fault, not Mark Zuckerburg’s.
