In 2001 after the 9/11 terrorist attack in New York, the US government announced that it intended to profile its citizens to better protect them. The citizens were up in arms because despite their fear of another attack, their distrust of large institutions compelled them to do so.
In 2004, Facebook was launched and they told us they intended to profile us so that they could better connect us with long lost relatives, pals and random people that may have similar interests. We welcomed the idea with open arms and voluntarily supplied our personal data to strangers.
