I think these concerns still need to be translated into real world repercussions before the average person is convinced. Right now it is certainly creepy, but does it really have a negative impact on my life for a company to know these things?
I remember an interview with Edward Snowden where it was shown how little people cared about privacy. The interviewer then translated the concern into "the gov can see your dick pics". That was a no-no for most people
