Again, I deplore the colossal waste of human effort and talent that is going into building a sophisticated panopticon for the noble purpose of better targeted advertising . For fuck's sake, what a waste of the best minds of our generation.
I hate when people say that people who waste time on Facebook just need to show some willpower. As you say it's some of the best minds working on it. Pitching the willpower of a 15 year old against the combined minds of the Facebook engineers tasked with keeping them on the site, of cause the 15 year old (or 50 year old for that matter) will lose. And all that, so some company can blast us with adverts.
It is sad that they chose to build themselves upon tracking / data-mining / advertising.
Even if they charged a nominal fee[0] of $1 per month they'd have nearly as much incoming revenue and much lower overheads without having to develop and maintain all that creepy stuff. They wouldn't have to play psychological warfare, they could just focus on providing a good product.
'Facebook is free and always will be'. But at the cost of being regarded as malevolent and, therefore, ripe for disruption.
[0] I apologise if this is not nominal to a significant proportion of the user-base.
