"Nearly one in two Internet users say privacy and security concerns have now stopped them from doing basic things online — such as posting to social networks, expressing opinions in forums or even buying things from websites, according to a new government survey released Friday.
This chilling effect, pulled out of a survey of 41,000 U.S. households who use the Internet, show the insecurity of the Web is beginning to have consequences that stretch beyond the direct fall-out of an individual losing personal data in breach. The research suggests some consumers are reaching a tipping point where they feel they can no longer trust using the Internet for everyday activities."

Google cannot sell advertising based on my eyeballs if I won't use Google Search, block ads, avoid Google Maps, and download video via yt-download vs. watching it on the far-less-convenient YouTube website or application.
Google have lost me to search, and several other products, for precisely this reason. I don't know the segment of the population I represent, but it is a segment.
A US Department of Commerce survey release this past week reveals that 20% of the population consciously avoids online activities already due to privacy and surveillance concerns. This isn't fully attributable to concerns over Google (and that almost certainly poses a subset of those dissuaded), but it is a surprisingly large effect of privacy concerns.
The trust factor you mention is a huge one. Cognizability is a wonderful word I've run across recently (from William Stanley Jevons' discussion of money). It refers to the ability to instantly and unambiguously recognise a characteristic or trait. Electronic devices lack cognizability of privacy.
Glass didn't do so well as I recall.
