I don't think it really subverts the message. The default browser style is simply unusable given the widths most people have their browser set to. A minimal stylesheet to bring it back to usability is reasonable. The point is that people have, at times, become a bit too obsessed with style, interactivity, pictures, colors, fonts, video, audio, etc. Sometimes, you just need to focus on the content. If a minimal stylesheet helps with that (just keeping a reasonable column width, and reasonable font size, to make the text readable), that doesn't really affect that message at all.
