Yes, the big guys suppress disinformation that is going to result in people put on ventilators, school board members getting threatened, racist recruitment, human trafficking, suicide and other things that are going to get people physically harmed.

They are shutting down qanon conspiracies, dangerous medical advice, advocating the violent overthrow of the government, and threatening violence against people.
