> Here is some anecdotal historical context. Recently my parents were reminiscing at a family event about mid 20th century small town American life. The local telephone exchange operator (always a woman) could freely listen in on any telephone conversation going through the switchboard. It was not unusual for a teenage girl to substitute for the regular operator. Everyone in town was at least vaguely aware. No one cared.

Would you agree to let your calls be recorded and posted on a website? How about when you call your bank and verify your identity? I truly doubt that "no one cared" but maybe less sensitive business was conducted over the phone in those days.
