Actually, I can sympathize with this guy. Too much of our private information is going out there all the time, and there really is no privacy any more. Example:
Recently, I got on Amazon to buy some underwear. I found what I wanted and started to order it, and when I got to the "size" part, before I got a chance to click on anything, a notice popped up on the screen saying:
[My name], based on other purchases you have made, the suggested size for you is [number]. I was flabbergasted! Besides the gratuitous invasion of my privacy, they had the size wrong. If I had followed their suggestion, the item would have been way too big!
I know, not exactly the same thing, but this person may have finally had his fill of sharing everything about himself, unnecessarily.
