@manton it may feel that way to you, but it might feel completely different to someone else. And in fact that's often the case.
That's why we need to be more concrete than just talking about how one person feels, because often enough that will be a setup to later feeling betrayed when someone else's feelings lead to them doing something unexpected.
When it comes to privacy in particular, we shouldn't go with feelings, we need to spell out the rules. Otherwise, you'll have people being surprised when what they felt was private ended up not being private.
