content: because both public comments and private thoughts will be monitored and controlled.  Technology is unfortunately quite advanced. Some of the tech they displayed in Batman movies a decade plus ago we thought of as "sci fi" was and is anything but. The super weapon Morgan Freeman was given access to that allowed him to give Batman info to 'save the day' towards the end, but only agreed to use on the condition that it be destroyed... the beacon/human radar system... does that ring a bell? To the common public that sort of thing is just cool movie effects. To people with the education and expertise to develop it, no, it's actually soft disclosure. I've heard they're doing a good job of leaking more in the next one. Monitoring thoughts, controlling them... there are public patents decades old that discuss these topics and how to do just that. ...and they are decades old and NOT classified. So again: more soft disclosure. It's everywhere, but most people think it's just 'fancy sci fi', or a 'neat story device' so they don't look into it. The Patent office records are public for anyone to read online: all it takes is time and effort.
