EDIT: a lot of people are taking my statement as meaning not to criticize Facebook. That is not it at all! It just means not to lose perspective. At least I still consider tobacco to be far worse, directly causing ~7M deaths annually with no visible benefit.
EDIT 2: Genuine question: has anyone studied the rise of fascism post-FB vs. pre-FB? It's not like dictatorships and far-right governments didn't get elected pre-FB. Obviously I am one of those who doubt FB's direct responsibility vs. it being simply a media narrative against a business threat.
