Why oh why do the people who care a Very Much Lot about privacy assume everyone else does too, or should on some moral axis? Like the very nature of not thinking of privacy as some value worth maximizing is in and of itself an Evil Act? Why does the idea that people are free and reasonable to give up an amount of privacy for convenience (or entertainment) break their brains so thoroughly? And why does it come in the form of insults and belittling language, such as this submission? You should be free to be private, I'll defend that to the ends of the earth, but I'm also free to not be quite as private, and if you won't defend that to the ends of the earth in kind, what's that about?
