>They are probably like me: if punctuation isn't on my keyboard, I don't use it.
LPT: on Android, pressing and holding a punctuation key on the on-screen keyboard reveals additional variations of it — like the em-dash, for example.
This is the №1 feature I expect everyone to know about (and explore!), but, alas, it doesn't appear to be the case even on Hackernews¹.
On Windows, pressing Win+. pops up an on-screen character keyboard with all the symbols one may need (including math symbols and emojis).
MacOS has a similar functionality IIRC.
And let's not forget that software like MS Word automatically correct dashes to em-dashes when appropriate — and some people may simply prefer typing text in a word processor and copy-pasting from it.
Anyway...

¹ For example, holding "1" yields the superscript version, enabling one to format footnotes properly with less effort than using references in brackets², yet few people choose to do that.
