I understand the complaint, but in this day and age, that's like being annoyed that your microwave and VCR have clocks. Everything is a social networking site now. I had to think for a minute in order to not include some form of profiles and user-to-user messaging in the last app I wrote.
I think it's just a generation gap, though—being younger, I grew up without any expectation of privacy from strangers, and I don't see anything wrong with that, really. I know that everyone else has just as many trite details floating around about them as I do, so there's no reason to single me out. It's like the sociological warfare of cars getting a steering-wheel-locking device/alarm/what have you, but in reverse: every person that removes their car's security is one more person reducing the probability that my car will be the one to get stolen.
