This whole article appears to be based on a misunderstanding (or at least an idiosyncratic view) of typography. Varying styles within a work can be immensely helpful, and is almost universally done. For example, headers tend to be written bigger to indicate a) that they're something different from the main text, and b) what their relationship to the main text is. Similarly, italic and bold text are used to impart additional meaning to various parts of the text. Many publications will use a different style for things like bylines and photo captions — again, because they are different things from the body text and this helps the reader pick out the parts of the page in a purely visual manner. It's even common to see parts of the body text stylized differently to indicate that they have a special function — for example, in a Q&A format, you'll often see the questions formatted differently from answers, or the identities of the speakers might be written differently from the words they said. So not only is this philosophy about typography not necessarily applicable to code, it's not even widely accepted for ordinary written text.
