The terms "missing" and "disappearance" of stars is applied in somewhat "plastic" manner.... Taken out of context, they could be misleading to "people from street".

Absolutely. Deducting that stars that aren't observed have "gone missing" because a theory predicts their observation is turning science on its head.
Back on topic, I watched Orion appear in the evening twilight sky last night, and could detect Bellatrix before Betelgeuse. Watching the two in averted vision later (thereby reducing effects caused by their different colour) also gave Bellatrix a small but reproducible advantage.
