Not uncommon at all to have no curtains. Portion of those that do, might use them for other purposes too (glare, light etc).

People will balk at giving a random friend their device but probably will be perfectly okay handing it over unsecured to a repair shop. People will be unwilling to show many body parts to a friend but likely perfectly fine showing them to a doctor.

That I do not want to show something to you specifically, doesn't mean I'm hiding something from you. If you ask me to give you my browsing history I may or may not. Depends on the reason. If it gets leaked to everybody I will be rather unfazed. But if you call me to tell me you're carefully examining the leak at this very moment, I will still feel weird about it.

Another example. The nearby grocery store knows what food I'm getting every other day. Would I like this information broadcast to friends and family in real time? No, would feel awkward. Will I go crazy if the list for the last 2 years gets leaked in an instant? Not at all.
