The topic was sharpening, and the differences in ways to do that. Abobe's programs are not even close to the only way to sharpen. In fact *most* users that actually get into the more sophisticated aspects of sharpening cease using anything that Abobe provides for that purpose, and shift to better tools.

Generic atributes of sharpen tools can and should be discussed absent references to specific implementations. When specific attributes are discussed it doesn't make a great deal of sense to look at low end products designed to appeal to the lowest common denominator, as might well be discussed in your "Abobe Tools for Dummies" manual.
