Facebook and all social media and internet advertising firms get to use detailed dossiers to target us with ads wherever we go online. That’s a conflict of interest, because it encourages a business model in which communications facilities try to addict us so they can sell us more ads. Unlike a phone network, which is not financed by ads, social media companies pick and choose incendiary content to promote. This both creates filter bubbles of conspiracy theory-minded communities and redirects advertising from legitimate publishers, such as local newspapers, towards ad monopolists such as Facebook.
