I can understand turning it on if you're doing something like going backcountry hiking by yourself, and turning it off when you're back.
But leaving it on all the time so people I know can open an app and see where I am at any given moment? That's creepy as fuck. There are people in my life who I trust, and care about me, but that's still creepy as fuck.
Or I'm not so risk-adverse that that I'm willing to give up my privacy for a miniscule possibility that something could happen where that would help me.
Yes, my wife can see me on Find My Friends, but that is because there is nowhere I am that I’m uncomfortable with her knowing about, and it’s nice that she can see when I leave the office to know when to put the kettle on. It’s a convenience between us, not a Big Brother spying program.
It's weird how divisive this topic is. I share with my parents, kids, and husband, and vice versa. It's cute to pinch up the map and look, mom's at yoga or whatever. It's not like anyone's sitting around all day staring at the map. I guess I'm lucky not to be haunted by control freaks past or present.
