  1. Indeed. And in fact not only science communicators, but also many professional astrophysicists (I am one of those) use the expression "dark matter" not to refer to a list of observational evidence, but rather to refer to a broad (although vastly unsettled) theoretical framework that could explain them: specifically, invoking some so far unknown form of matter, as opposed to theories of modified gravity or modified dynamics, which are commonly regarded as alternative to dark matter. Most of the confusion probably arises from the fact that Angela is adopting her own definition of the expression "dark matter" (which to me personally sounds perfectly reasonable and after you accept it the whole reasoning is flawless), but does not really match its most common usage.
