People like transparency, people are drawn to dangerous things. Hiding shit behind closed doors or being super paranoid is not cool, and will not get you fans.
The only security most people need is herd security. As long as your data can blend into a mass of other people's data to the point where you're just an anonymous face in the crowd, there's no harm. Sure, if you're some important individual who can be compromised by someone motivated enough you might have something to be afraid of, but most people never rise to that level of importance.
