Exactly. FB has done some crappy things (changing default without clear communication of consequences being a major one http://mattmckeon.com/facebook-privacy/) that LEAD to CA being a problem. Im willing to bet 99% of people dont realize that WHEN they signed up for facebook changed the default settings, and that their defaults might be different than their friends. And letting developers have access to "public data" can be debated, especially when they are playing so fast and loose with what gets posted publicly by default.

BUT, the developer itself is the one that got people to fork over their friends info, and having friends that will give up their friends privacy to play a personality quiz speaks way more to the public than it does to facebook.
