There's a difference between "weird people could choose to do this creepy thing and violate my trust" and "not weird people could forget to turn off this slightly less creepy thing and still violate my trust" Both of these suck, but honestly I don't appreciate that Apple is making me feel uneasy talking around my friends with Apple Watches. Not because I don't trust my friends, but because now it takes extra work for them to not do something kinda creepy.
