This is not obvious to the average person outside of the industry. For example, most people would expect that text typed into a form field without clicking submit is private and has not been sent to anyone. It is obvious to a software developer that secretly sending the text back to a server while the user types is easy to implement, but posting an agent to read over someone's shoulder while they write a draft which they may choose not to send at all does not become morally acceptable just because modern technology has made this more practical than hiring a PI to watch through someone's house window from a public street.
