In the wake of the IPO debacle, Steve Coll spells out why he's leaving the site:
Facebook’s huge valuation now puts pressure on the company’s strategists to increase its revenue-per-user. That means more ads, more data mining, and more creative thinking about new ways to commercialize the personal, cultural, political, and even revolutionary activity of users. There is something vaguely dystopian about oppressed peoples in Syria or Iran seeking dignity and liberation inside a corporate sovereign that is, for its part, creating great wealth for its founders and asserting control over its users. …
It takes a while to find it, but if you are a Facebook user, there is a small settings button entitled "deactivate account." If you click, Facebook displays the faces of people "who will miss you." If you are determined nonetheless to depart, and scroll further down, you are required to choose a "reason for leaving" before you are permitted to go. Unfortunately, "inadequate citizen rule" or "doubts about corporate governance" are not among the choices. From the available list, I went with "I don’t feel safe on Facebook."
Coll is not alone, but Rebecca Greenfield isn't worried:
In no way does this indicate a coming mass exodus. These people aren't starting movements, rallying the people of the Internet like Quit Facebook Day tried (and failed) to do back in 2010. These are just some conscientious objectors who don't want to support a company they don't believe in.
