Consideration of this incident as terrorism is a great indicator of the position of private businesses within US policy. Corporations are, for all intents and purposes, a core contingent of the US government and its policy, hence why the corporate media+capital class+politicians are treating it as such.

I’ve heard Department of Government Elimination but that works too

Deliberately sabotaging your job as a government worker (assuming you’re not working in a military industrial complex or enforcement job) plays directly into the right’s framing of government as inefficient. It’s important that public-facing positions be competent to foster public trust; after all, those positions are what conservatives dismantle first as pretext to abolish an agency. After public discontent sets in through first-hand experience dealing with understaffing, those public services become ripe for privatization.
