Sounds like you're doing a little monday morning quarterbacking here. Neither of us heard the dad's tone or saw his body language, so neither of us knows just how strongly he was communicating "she's going to Youtube because she hates them." But, if we are to judge on the words alone, nothing in that phrasing says "mass shooting in the offing." Most people who go to the offices of a company they have a grievance with are going there to complain or raise a ruckus, not start shooting folks. As evidenced by, you know, the extremely anomalous nature of this shooting. ("extremely anomalous" as in "mass shooting of a corporation you're unhappy with", not just "mass shooting," because those are a popular pastime in the US.)
