People don't want their privacy violated. It doesn't matter what data you're collecting. If you peer into my windows every day in order to document the colour of the paint on my walls, you don't get to use a defence of "I was only interested in unidentifiable information and besides, they wouldn't let me do it when I asked nicely". Software installed on my machine is in a privileged position. It has more access to my personal files than my close friends and relatives. I'd rather that software respected some simple boundaries.
