I can't bring myself to send a corporation a constant stream of extremely personal data when I know they absolutely will sell/leak all of it along with the countless assumptions they'll make about me using that same data.

It'd be nice to have the information a ring or watch gathers as long as it stayed local. I haven't seen many products offering that though. The thought of not being able to continuously profit from surveillance is just too painful for many companies to bother creating a product aimed at the consumer who doesn't want to be spied on I guess.
