I think most people do care about privacy, but they're not being given much of a choice here. Their friends are on Facebook, so the only way to share pictures with all of them is through Facebook.
From my point of view, I do care about privacy, beside I don't use mobile phone, I don't want to. Since whatsapp isn't an option for me, messenger app is only way to be in contact with friends, family. (I have iPod Touch) Considering I'm traveling often, I need to use it. I'm not fan of it, but I'm not against either. In the end we are product of Facebook and #deleteFacebook is a joke.
Maybe most people just don't care all that much about privacy
Not only that. Most people welcome the attention. The people who are fighting for privacy of their friends and family are the ones who don't get it. Friends and Family want to be out there, in the public eye, liked and commented on.
