That would be the "other concept" referred to in the grandparent.

It wasn't very clear what you meant by that. The other use of "utility"? Presumably you didn't mean this:

utility - "a public service, as a telephone or electric-light system, a streetcar or railroad line, or the like."

...but what did you mean?

Actually I don't much care. You are just bitching about standard terminology. That is not my problem.
