I am baffled that people like yourself are not concerned in the least.
I grew up in an Eastern Europe Communist State where this kind of personal surveillance was the norm. People went and wrote down all their interactions with others. You can see these documents now as the former secret police archives were published (what wasn't destroyed to protect the higher ups).
It's amazing how the most innocuous remarks can be used against yourself in an unbelivable twists. Just an example:
Person A criticized person C, which was his boss, as being incompetent, to person B, which was a secretly delator. Person B went and reported to the secret police this tension, as he was payed on the number of pages he would write.
The secret police compiled a weekly report of stuff that would happen, in each company, and send it up to the party for review. It just happened in the party that somebody who saw the report had frictions with that Boss, and he used that report to push the Boss around. The Boss thought that person A himself wrote the report, and used his connections to get person A fired, and banned, on the party line, from ever having a qualified-work position again - ie he could not be an engineer, teacher, or anything, leaving him with just construction work or janitorial jobs.
How often do you bitch about your boss? How would you like that your boss gets reports about what you bitch about him in your own home? How would you like that what you say, no matter how private you want it to be, is always recorded?
I'm astounded by the fact that people see nothing wrong having these devices always listening to them.
