"Its the generations of people who have, over the last 10 years, grown up to assume that their personal lives are of interest to others, and wish therefore to capitalize/profit on exposing their life to strangers." - Say what? Most people aren't looking to capitalize/profit on anything, they just want to share bits of their life with others that they count as their friends.
Most people are definitely not aware of what happens behind the curtains. The fact that there's a big gorilla in the room watching everything they post and profiting of that is the problem.
And that gorilla is Facebook.
