It was always difficult to differentiate the Flash Player from the Shockwave Player when discussing one or the other or one from the other.
Seems to me that in the past they called this "Adobe Shockwave Flash
Now it looks like they more simply & more clearly call it "Adobe Shockwave Player".
At least that is good
I would think that for the majority who may have it installed, likely a default install from some store-bought computer, they never actually have had the need to use it, so the obvious thing to do, if you don't need it, is to uninstall it.
(As if Flash alone isn't bad enough
