I don't think the distinction is as clear as you imply. Facebook is a multinational corporation that is arguably more powerful than many governments, and it can and has swayed elections.
At what point are Facebook's "moderation" decisions "censorship"? You're effectively saying that it's only when moderation is driven by some kind of government policy, which completely erases the factors that actually matter in evaluating the danger of any given suppression decision, ie. understanding of harm, considerations of power and oppression, etc.
