“I have nothing to hide” is the most common one I hear. I usually respond with “then why do you close the door the bathroom?”, “why do you wear clothes?”, or “then let me read all the messages on your phone”. Everyone has something to hide. Another one I hear a lot is “These companies already have all my data so it doesn’t matter!”. This is a really bad argument because if you forget to close the bathroom door once and I see you pooping I doubt you would then stop ever closing the bathroom door since I’ve already seen you pooping once.
