As is their right. The fact almost no one bothers to actually read the TOS for FB is their own fault. It lays out, albeit not clearly, that FB collects data from your personal page and whatever you share and they can then do as they please with that information. The fact people blindly share intimate details of their lives on a website has always baffled me.FB feeds the feds data. Sometimes even without a subpoena.
FB and all it's associated entities are nothing but flashy data mining operations to sell advertising and make The Zuckerbot 2.0 more money. If you can't see that or refuse to acknowledge it, you forfeit your right to complain about what is done with said data.
I never joined FB. I always saw it as utterly useless and time has proven me right.
