Many of us who aren't quite as old-school as RMS still treat electronic communications in this way.
Yes, there's communications we'll make which are more privileged, but we understand that fundamentally the system is open to observation and snooping. If we've got something to say we don't want others to know, we say it in person, using crypto, or through code (formal or informal) which will be difficult for others to understand, if at all.
And there's still good old mail. First class will often reach someone faster than they'll dig through their mail spool these days (and a letter indicates an investment in communication), even next-day mail is pretty cheap (much less expensive than FedEx).
