You are not always the target, but leaking data like this empowers those that may use it against someone else. I mean to say, you are providing training data. People who move-like-this-at-these-times
also have these other tendencies... It's like fusion sensing.
Same with secure messaging. You might not care that [insert boogeyman here] know what you're doing all day, but people you interact with may be harmed by you being leaky.
Anyway, the whole point is your lack of imagination is not a good reason to embrace surveillance. Rejecting surveillance on principal slows down our descent into a panopticonical hellscape.
