If an interpreter wanted to defend causal contextuality, this would entail abandoning FM, at least for observables of the type f(Q) (non-maximal observables): Since their values causally depend on the presence of certain measurement arrangements, these arrangements are causally necessary for the values to come about, thus the values cannot be present before the system-apparatus interaction, and FM is violated. As an advantage of causal contextualism the following might be pointed out. It does n
