Apple "advocates" never said any of those things. I'm going to give you the benefit of the doubt and assume you actually did read this stuff, so let me just say, you need to learn how to recognize a straw man argument when you see it.
Apple "advocates", including some in this very thread, do routinely dismiss as unimportant, sucky, etc. every pre-Apple contribution in some of these categories (especially smartphones and tablets). I generally think they're trying to emphasize the importance and originality of Apple's contribution, but I can see how someone else might interpret that as saying "Apple invented X".
