Many editing tools support double or triple hyphen that convert automatically to em dashes. On Android it's trivial to write an em dash (easier than say the percent symbol).
I even have a plug-in that converts some hyphens to em dashes on my blog.
Rendering judgment on someone who published something on their own site without knowing their stack reflects more on you than him.
Not the point, and no it doesn't. 99% of anything published since ChatGPT launched, that contains em-dashes, is suspected AI slop. Very few writers will make the extra effort to manually insert an em-dash - in fact hardly any writers even know how to or where it should be used.
I am merely stating how people now view em-dashes, not how I wish things were.
There was another submission just a few days ago that analyzed em dashes in HN comments pre and post LLMs. The amount of em dashes has not even doubled (i.e. a comment with an em-dash is still more likely to have been written by a human than an LLM).
"Sorry, you're just plain wrong" that's a bit of a leap, when I'm stating my interpretation of what the general opinion is, not how the world should be. Have you interviewed everyone? (I don't just mean the small subset of everyone who posts on HN).
