There's nothing "more" to know, people do not like being spied on and no one would sign-up to have someone watch their home if that meant everything they said was being monitored. People understand and are afraid to say something for fear that it will come back to haunt them.

I think your perspective is a valid one. However, I don't think everyone realizes they are actually being spied on or to what extent. The media says one thing (not always the same thing) and government denies it. I believe to many people that's enough controversy to avoid thinking too much about it.

And to pre-empt any argument that I may be too faithless about people's natural proclivity to protect themselves, consider something as as epic and clear-cut as climate change. I can't think of a better example of something so threatening to society yet so popularly disregarded.
