Wow that post is bad. The author clearly never actually attempted to understand what POSWID actually means and where it is coming from. Perhaps, instead of looking at Twitter, they should have opened Wikipedia. Or, better yet, Stafford Beers books (though admittedly, he was a pretty atrocious writer).
The follow-up is slightly better. But still not very convincing, IMO. They get far too stuck on a literal interpretation. Of something that self-describes as a heuristic.
