Focusing on Facebook exclusively (for now) will give the public a real, indisputable, concrete example on why data mining is terrifying. If you start babbling on how "everyone's doing it" then you take away much of the importance and seriousness of the topic. People start going "you didn't know that? Of course they do" and "yeah, what can you do about it, right?" and just shrug the issue away. But with the specifics of Facebook and CA, you know that something can be done, and that not everyone has been doing it the same way and at the same magnitude. Even if it's just Facebook, it's a step forward. You can't expect to take down all internet giants at once.
