HTML support client side, and required libraries are crazy complex compared to gpg integration. Yet that was done, and never meant to be.

Same for images inline, and the idea of attachments was an add-on. Other examples abound.

While I don't use html in my emails, it's effectively a standard now. So much so, that I have to prod some corporations to fix their stuff.

My point is, the "email was never meant" ship sailed decades ago. Change happens.

And there is no way to encrypt anything, ever, and send it to someone, who can't see it, and then copy it and send to others. A person can take a screen shot, or just take a phone and take a pic of the screen! So even if it's not simple, this problem is a non-solve, because if a human can read it, it can be copied to others.

Which means, I do not believe your criticism on this point is valid.
