Yes, in order to paint a picture, one must draw the odd brush stroke. I'm a privacy-conscious, non-car owning urbanite programmer, but I accept and am comfortable with that most people (particularly in the US for car ownership) regard having a Facebook account and owning a car as indicators of some minimum amount of social status.
I love not having a car, and think Facebook is for people with lots of spare time, but this doesn't invalidate at all the results of the survey.
