For me, it's the privacy. So many of the "smart" devices now have cameras and such that can be hacked. I keep a piece of athletic tape over my camera on my laptop so that if someone hacks in, they can't see anything. I've seen programs on TV where they show how easy it is for someone to hack into your laptop camera and watch you, even when you think the camera is not on/being used. And I am certainly no expert when it comes to technology, so I wouldn't know whether it was possible to hack into or not....so I'd rather just not have a screen in the room where I shower, etc. They can't hack into something that's not there. And maybe they couldn't even if it WAS there, but I don't want to take that chance. Just like some people not wanting to post pictures of themselves or their kids on a site like this. Statistically, that chance might be low of anyone using that information to stalk you, etc....but if it makes you feel safer, you do what feels right.
