By being friend with someone on Facebook you already make your data available to this friend. Your friend can show this data to anyone curious about you by showing his screen or by talking about what he saw on your profile.

An app on Facebook is only an automated way to ask your friend to share data he/she has access to. You cannot both share data with your friend and expect him/her to not be able to share it with 3rd parties.

If you don't want your friends to be able to share your data you don't become friends with them on a social network and/or you don't share data with them.

You don't tell to your acquaintances things you don't trust them to keep secret. And you can't expect them to keep secret things you share with every acquaintance

I tell my relatives repeatedly to not take pictures of me if they're going to share them on those platforms. This whole thing is a problem with people's complatiency with technology and especially the coorporations taking advantage of it.

You know what? I, and I’m pretty sure a majority of people, would rather just regulate Facebook to death. You jump through hoops to maintain your privacy, I’ll lobby for change to existing laws. Meanwhile you tell people how they’re just not into computers enough, or not hard enough on friends and family.

Let’s see which prevails.
