Thank you for clarifying! So it's just my phone number that will be striken-through.

This is something I've never liked about org-mode. Markdown was designed to be authored in existing tools, so its conversion of ASCII to Unicode quotes makes some sense. But Org is defined by its Emacs implementation, and Emacs has always had electrified punctuation support. There's no reason to export -- as –, and therefore need to deal with escapes, etc., when you can make -- insert – and export literally.
The fancier the editor, the fewer special syntaxes you should need in the format.
I'm not sure I understand that. You need to customize the export behavior because everyone doesn't prefer the exact same thing. While you prefer not to auto-convert to en/em-dashes, I prefer that. So having options (what you refer to as balkanization) is good.

Didn't follow that. What incompatibility is this in reference to? Which parser? Of which flavor of Markdown?

How else would every user get their export behavior unless customizability is added? Taking the same example as yours, I am glad that "--" does the job of "–" or "–".
I know of one Markdown parser (Blackfriday) that adds a similar en-dash/em-dash conversation like Org exporter (and is enabled by default in Hugo). So the customization is needed by a sizeable number of people.
In the end, it's alright if you don't prefer Org mode or like the option to have options. I presented the ox-hugo package for folks who like blogging using Hugo, but don't want the leave the comforts of Org mode. I am not enforcing Org mode on anyone.
Org-mode is an amazing tool and I use that tool every day. But to the extent there's an org format, it's not very good, and it's less interoperable than Markdown (the interoperability problems of Markdown are cited by the author as a major reason to avoid it).
I didn't write anything about ox-hugo or Hugo, and I don't know why you brought up either.
