But the main takeaway from the poll is that Americans express very high levels of concern about the threat to their privacy from social networks, cellphone providers, web sites “such as Google, Amazon or eBay” and the NSA. Roughly 70% said they were concerned about each, with only around 30% not at all or “not too” concerned. It is interesting that there are no significant differences between Americans’ concern over government and private-sector spying. Perhaps the reality of the Surveillance-Industrial Complex is sinking in.
