Facebook did not “scrape stuff for free”. People willingly gave FB their information.
RMS explains this much more eloquently than I do. He doesn't have a Facebook account, but he's all over Facebook, without any control, desire, or influence.
Many people set up Facebook accounts to have some control over this. Without an account, I can have nasty things about me on Facebook. To have controls over that, I need to agree to a contract with Facebook which gives away other stuff.
Their shadow profile on me was very solid, it seems.
