I've been thinking the privacy settings here aren't actually privacy settings (because they're full of holes) but rather *exposure* settings.
I think exposure controls (i.e how many people *will likely* see things) are great, but maybe the features should be renamed to reflect that they control exposure, not privacy (i.e. how many people *can possibly* see things)?

Okay, this seems to have resonated with a lot of people so I'm gonna just make an issue on GitHub. Thanks all :)
