Seems like a semantic game to me. Does the word "evidence" imply materiality? It makes no difference, really, because immaterial information, whether or not it is called "evidence," does nothing to boost our confidence in the proposition under consideration. A green apple, nay, a whole lifetime of non-black non-ravens. does very little to persuade us that all ravens are black.

The green apple does not prove anything other than that at least one apple is green. It may be "evidence" of lots of things, but only in a binary sense, i.e., only if "evidence" is defined as any observation consistent with a proposition, whether or not material. Inductive inferences are not based on whether some observation is evidence in that sense, but on whether that information is material to the inductive inference that the proposition is true. The green apple fails that test.
