Excerpts:

Voltaire was right when he said "Those who can make you believe absurdities can make you commit atrocities." And social media lets authoritarians push absurdities to millions of people.

Freedom of speech is not freedom of reach. Sadly There will always be racists, misogynists, anti-Semites, and child abusers. We should not be giving bigots and pedophiles a free platform to amplify their views and target their victims.

Zuckerberg says people should decide what's credible, not tech companies. When 2/3rds of millennials have not heard of Auschwitz how are they supposed to know what's true? There is such a thing as objective truth. Facts do exist.
