We should see Facebook as a drug store which its top kingpin, Mr Zuckerberg sell its social network 'drugs' to billions of his users, which when abused over and over again, the results are always never positive and messes with your dopamine levels. Because of the social connections, followers and inertia, it is harder for friends and family to leave.
Apart from its flagship product, social network 'drugs' it owns includes Instagram, Messenger and WhatsApp. The fine-print is if you mix that with trolls, disinformation and bots it equals never-ending reactionary anger. Very unhealthy for you.
