I’m not really well versed in the history of consumerism, so I ask: Is there a common pattern to what happens with companies which produce harmful products for their customers? Facebook is by no means the first company to do something like this.

E.g. Which cigarette company went furthest in marketing to children, are they still in business? Did any car companies refuse to include seat belts after their safety records were prooven, did they loose good workers as a result of that stubbornness?
