I think you've missed the core thesis of the article. That post _wasn't_ technical writing. It was marketing disguised as technical writing.
It was way too technical to disqualify it as not being technical writing. Writing can serve multiple purposes.
It’s marketing that is also technical writing. Most companies do this, and IMO we should prefer this over the alternative (which is corporate blogspam).
