I grew up as a kid in a country ruled by Securitate [1], one of the few institutions that rivaled the East-German Stasi when it came to spying on its own citizens, and as such I'm very, very perplexed of why would anyone bring in a listening device in his/her own house out of his/her own volition. And those people even pay for the privilege of having their home-lives actively monitored and listened to almost all the time, it's crazy.
