In general, plaintext protocols of any form should be met with the same derision as something like telnet would today. Encrypt all the things. We need the very idea of sending something like plain ASCII beyond your computer to be offensive at its core. Considering passwords are often stored in plaintext and companies think this is no big deal, I'm not sure how well that will work. Without proper trust models in place, this won't solve all the problems, but I feel like that's what the culture of communication on the Internet has to look like. It has to be done by the engineers at the protocol level, and application developers have to adopt it. Servers and other peer-to-peer clients should refuse to speak plaintext. Focusing on things like getting people to use PGP, OTR, etc, is hopeless and will only work with other privacy geeks.
