"My sole goal at this point is to push toward preventing Facebook from abusing those of us who choose not to use Facebook"
You and me both, but frustratingly I hear that Facebook creates something called 'shadow profiles' (which Zukerberg claims he hasn't heard of) for people that are related somehow to users but aren't users themselves. Who knows what personal attributes are stored in such profiles as they farm data from all the sources they have access to??
So, you are a user of Facebook even if you aren't, just without any opt-outs or other privacy controls.
