Stop telling people to stop using stuff. What happened to the good old fashioned suggestion? Guess doing that doesn't provide and SEO/controversy juice.
Linking to my past comment on this [1] to avoid dupe comments.
There are, of course, web email services that purport to encrypt messages. But they store encryption keys (or code and data sufficient to derive them). These systems obviously don’t work, as anyone with an account on Ladar Levison’s Lavabit mail service hopefully learned. The popularity of “encrypted” web mail services is further evidence of encrypted email’s real role as a LARPing tool.
