Riddle me this?
The claimed reason for collecting users' personal data is targeted advertising. But has ANYONE ever received a truly targeted advert? In my experience, they seem to fall into one of two camps; "people who bought this, bought that", and those bloody things that haunt you after a purchase based on the principle that since you bought a tap washer yesterday you'll be in the buying zone for more for the next two weeks.
So no, it ain't for targeted advertising. What then...?
