KJ Costello no longer visiting?

TL;DR - the reporting of the fact is perfectly fine, legally and ethically, so long as it is just the transmittal of the fact and not analysis or creative content.

In Feist Publications, Inc. v. Rural Tel. Service Co., 499 U.S. 340 (1991) the U.S. Supreme Court sets out the standard pretty well:

"The Copyright Act of 1976 and its predecessor, the Copyright Act of 1909, leave no doubt that originality is the touchstone of copyright protection in directories and other fact-based works. The 1976 Act explains that copyright extends to "original works of authorship," 17 U.S.C. 102(a), and that there can be no copyright in facts, 102(b). A compilation is not copyrightable per se, but is copyrightable only if its facts have been "selected, coordinated, or arranged in such a way that the resulting work as a whole constitutes an original work of authorship." 101 (emphasis added). Thus, the statute envisions that some ways of selecting, coordinating, and arranging data are not sufficiently original to trigger copyright protection. Even a compilation that is copyrightable receives only limited protection, for the copyright does not extend to facts contained in the compilation. 103(b). Lower courts that adopted a "sweat of the brow" or "industrious collection" test - which extended a compilation's copyright protection beyond selection and arrangement to the facts themselves - misconstrued the 1909 Act and eschewed the fundamental axiom of copyright law that no one may copyright facts or ideas."

Without the ability to copyright, there is no legal protection to the dissemination of such facts. However, as I have discussions with clients on a fairly regular basis, just because it's not illegal and you have the ability to do something, does not mean it makes sense to do so in practical application. As has been stated above, the recruiting media world is fairly small, and angering connections is not a wise course of action.

So here, it is my personal opinion that reporting Costello is potentially not coming is perfectly acceptable so long as the information is limited to that singular fact.
