Org-mode does have certain fragmentation - every Emacs config for Org-mode is different from another - there are entire packages built on top (and they drastically can change the behavior of entire system) - Org-Roam, Howm, Denote, Org-supertag, etc. Also, for what it is made for, Org-mode is widely successful - there's really not a single contender that can be used alternatively, there's literally no good replacement for it.
Comparing Markdown and Org-mode really makes no sense - different ideas, with different design goals, use cases and applications.
One of the arguments of the article is that there is a fundamental difference: Markdown was created as a small subset of syntax elements. Therefore, there was a high demand on syntax extensions that were added in a chaotic fashion.
Orgdown already comes with more syntax elements that Markdown probably will ever get. So I do see a clear argument for the case that "unstandardized additions" to orgdown are less likely in addition to the fact that there aren't any.
Though at its current state, it wouldn't need that much more, because it can already do tons of stuff that markdown cannot even start dreaming about.
