With the number of people concerned about privacy

That number appears to be very small, all things considered. Out of everyone I know, literally one person cares about privacy. My mother. She will even go as far as to only use her first initial online instead of her name if she can get away with it. However, she uses Chrome all the time because she doesn't understand that your browser also tracks you.

I think that's what it comes down to. A mixture of lack of public interest, and lack of public awareness about tracking/privacy in general. If people can't immediately see how having their data harvested will inconvenience/hurt them, they simply don't care.
