Do you happen to have curtains in your house? If so, why do you care that strangers can look inside and see all the activities you're doing in there? You're not a corrupt politician, you are not part of the mafia, .. So don't just give out a free pass to track you when you got "nothing to hide", especially to strangers. Not knowing what one will do with your seemingly non-interesting data should be enough reason to not give it away. That's at least why I care.
Theox, I can't believe your statements, coming from a Romanian. I spent a couple of months there, late ninetees, and I still remember people telling me of how afraid they had been, not only of the government or their police or intelligence agencies, but also of each other, as many remembered being reported to the government by their fellow villagers, for little "crimes" as not reporting a sleep-over at somebody else's house in a different village.
