well that's fair, but sounds more like a email client issue than an actual issue with gpg/pgp. My client shows pretty clearly when it gets encrypted. But maybe I am oblivious.

I tried to find something in the article that bothered me, but I don’t find it very convincing. Points like "someone can forward your email unencrypted after they decrypt it" are just... well, yeah - that can happen no matter what method you choose. It feels like GPG gets hate for reasons other than what’s actually mentioned, and I'm completely oblivious to what those reasons might be.
