Since they are set open, I assume they are actually using them as if they were en-dashes and not em-dashes, which the more common style would be to set closed, but I’m guessing, in either case, the reason is “because you can type it on a normal keyboard without any special modification, Compose-key solution, or other processing, and the author doesn't care much about typography”.
EDIT: Though these the days it could also be an attempt at highly-visible “AI didn't write this” virtue signaling, too.
Yes; because - is on the keyboard and — isn't. (Don't tell me how to type —, I know how, but despite that it is the reason, which is what the parent comment asks about.)
It's just that I have the feeling that people avoid using the actual em-dash in fear of being accused that the text is ai generated. (Which isnt a valid indicator anyway) Maybe its just my perception that i notice this more since LLMs became popular.
