Some differences:
- Governments have far more power and resources to skew the narrative.
- Governments are less accountable than any private individual or organization. Organizations are at least accountable to shareholders, the rule of law, and the government they operate under.
- Domestic organizations are at least ostensibly committed to maintaining the system, many foreign governments literally want to tear the system down.
- Governments have a historical track-record of tyranny, and have generally caused more harm than private organizations.
