Even then, the surprising, and technically not against TOS, open secret to every single social app that leverages it, is the comparative ease with which one could scrape a user's peer nodes' entire public history without explicit permission from said node.

Whether or not you like contracts of adhesion, Facebook is taking advantage of people.

Personally I quit Facebook upon signing up the first time in 2009. I friended a real life friend then 20 assholes from high school saw that action on my friends timeline and tried friending me. Right away I closed my Facebook account and never signed up again.
It was obvious back then Facebook shares my actions I don't want public with anyone they feel like. If you don't want them to do that then you shouldn't use the service.
