Totally agree, Dan.
I went on a site the other day to register a purchase (cannot remember what it was now).
They wanted home phone , email , street address. I thought that they don't need all that so went into registering under Facebook ID, they wanted access to all my posts, pictures, friends etc.
I did not register, as we are covered by lawful warranty in this country..
Makes one wonder why they need all that info?
I don't mind if other members disagree with my comments.
I don't profess to know everything, and I may learn something new.
