I had a friend at work who said "People who pirate stuff are just as bad as burglers" to me. I had just been Burgled 2 weeks before Christmas.
I replied "Right so I'm as bad as the smack heads that robbed my kids presents, is that what you're saying?"
He did that thing folk do when they look like a fish breathing then tried to backtrack, but that's when he became a "work colleague" again.
I had a friend bring up this very topic this weekend and I replied "What would be more creepy and more likely is that the ad giants have algorithms for working out what you'll buy that are that good that they know what you want before you do and you're just noticing how good it is"
