Weird. I'd rather say that tech users would use shorter version because there should be no diff between www/nowww

Why should there inherently be no difference?. They are simply nMes.

I’ve had people tell me things are broken when I send them to foo.example.com and they insist on typing the nonexistent www.foo.example.com.

Exactly. The point is that there is a difference between www and nowww. The only reason they usually lead to the same result nowadays is a social convention and those can change arbitrarily. Tech people are aware of this but non-tech people notice and learn this convention by association and might be (and from my experience, are) unaware that it is not a technically guaranteed one.
