This is not a complaint. I don't care to read what they're sending me anyway, and the wall of visual garbage that greets me when I open one of those messages has trained me to reflexively hit delete and move on.
shrug Maybe it depends on the type of stuff you're getting.

Most people use GMail as their email client, so even when they read plain text emails what they actually see is HTML email. The only difference is typeface, but you can configure that.
I don't see any obfuscation happening in the emails shown in this article. Rather, the article's suggestions give even more emphasis to the text.
"Grr HTML bad" is not a very defensible position.
> In my mind, email, or text communication, is not about presentation but is about textual content.
It was recognized before email even existed that presentation is fundamental to textual communication. Cf. the works of Jan Tschichold and Marshall McLuhan to pick two arbitrary examples.
The more ways you have to convey the information, the better, imo.
