But uncle Joe and grandma Margaret don't care about confidentiality. If they did, they wouldn't crab about that shifty Snowden guy, and they would donate to the EFF. They just don't want their Facebook login stolen, or their banking login sold on some forum, or their family photo gallery erased. Confidentiality, for the unfortunate majority of Americans anyway, just isn't a selling point.

That is confidentiality, no? If login credentials are transmitted in the clear then anybody listening can impersonate them. That's exactly what FireSheep demonstrates.
I disagree, and so does the IETF: Pervasive Monitoring is an Attack[0].
