You seem to be working from an arbitrarily tight definition of hole that's excluding black holes. There are lots of different definitions of "hole", and I don't think black hole is misleading to the layfolk. They're typically dark, like some holes. And like some holes, stuff falls in and generally doesn't survive the journey. To the physicist, they know that the words "black hole" just reference a physical object with lots of mathy description.
