I don't think your criticism is very accurate here. Wolfram Language code doesn't show up until the second half of the (very long) article, in the sections where he is explaining how to represent the mathematical concepts in the Wolfram Language. In fact, in several cases he mentions the traditional mathematical notation and follows it with the Wolfram Language notation. What's strange or arrogant or egotistical about this? Yes, he's the founder and CEO of the company that created the language, but that doesn't strike me as a problem. It's a good language for doing this sort of thing, and it's pretty clear that he's genuinely interested in both the mathematical concepts and how to create a programming language to represent them. This is hardly just content marketing blogspam.
