Why does anyone have to tell you the AIBU, @Againstmachine? Do you have some sort of editorial power or responsibility, to ensure that the sacred bounds of AUBU are never breached?
Frankly, this is not the moment for such nit-picking pedantry, and this is not the place for it either. People are genuinely saddened by this news, and it would cost you nothing to respect that, and to stop trying to derail the thread.
You don’t have to feel sad, or want to discuss the news, but it is just nasty to try to upset people who are sad and do want that discussion. And saying “Ner, ner, ner - you can’t stop me posting wherever I want” (I paraphrase), just looks immature and childish.
