This is an orthogonal issue, not a bigger issue. The point of end to end encrypted email is that it doesn't sit unencrypted on the mail server. Whether it sits unencrypted on your client or not is something clients should work on, but it doesn't mean that using encrypted email in general isn't hard. I could equally say that the fact that metadata such as senders isn't encrypted is a problem, but that's not what this article is about. We can have that discussion, here just probably isn't the right place unless you're going to tie it back into why GPG is so hard to use somehow.
