The data must flow both ways, that way the NSA/GCHQ only have to deal with one company. I read an interesting article earlier about a woman that wrote a book review that Amazon pulled stating she knew the author, the only thing linking her to the author was following them on Twitter and Facebook plus being at the same event as them a few months earlier. Makes you wonder how much information there is floating about on (nearly) everyone.
