I'd also like to add that most people don't understand what can be done with all this data. If you start explaining even simple examples so people they think you're a conspiracy theorist, unless they're already a conspiracy theorist then they "already know". But a simple example like the story of Target mailing coupons to a house with a pregnant teenage daughter. Many people still think that's impossible or the father hard to be really dumb not to notice the girl was pregnant. As techies we look at that sorry and say "well duh, that's not even that difficult" while non techies have a hard time comprehending how that's possible. This is a huge disconnect. So I'd argue that even though some people understand that they're giving up their data that they don't understand how it can be used.
My favorite example is just waiting for someone to mention how Facebook must be listening to them because they had a conversation in private with their friend about something, say an extremely new found interest that "they've never talked about before ever". I'll explain how the process works and how we can connect certain things together, how there is proximity, and knowing social groups and structures. That while the microphone would be useful, it isn't necessary for a good guess (and that it is a guess). I think most people here would say "well duhh" but try it with your relatives, see how crazy they think you are and that it has to be a microphone.

There's a big disconnect, this is a problem.
