You are using Facebook, and Facebook is using you and your data.
"Using you" has a negative connotation, like a bad relationship. So what does Facebook do to "use you"? It shows tailored advertisements. By that standard, nearly every commercial entity on the web is "using you".
The article continues with non-Facebook-specific privacy issues, mostly focussing on law enforcement being able to access your data. If you got a problem with that you should take it up with your representation, not with those that simply comply with the law.
The problems with data aggregation are correctly identified, but not specific nor directly related to Facebook.
If an employer won't give you a job, because she found a drunk picture of you on your public profile, I really see only two people at fault: You yourself, and your employer (and maybe your local laws that allow for this to happen).
I think it is weak to point the finger at Facebook, when all they seem to do is facilitate you and others to give them data voluntarily.
