Facebook + Google hold similar levels of power as governments over our lives, and so should adopt similar structures. An independent judiciary, review bodies, ombudsmen, aldermen, etc.
Yes, because the judicial system is free of politics and nothing can ever go wrong by giving the government more power to police what can be done on private platforms.
> We already hold similar levels of power. We can just not use Facebook and Google.
Common argument. Not a great one, because some things are only available through Facebook, and not being there can complicate your in-person life significantly. But, since I'm not on Facebook, I have to admit that it's good enough for me.
> One needs neither of these services to live a normal life.
A step too far. Normal people have Facebook and use Google. One needs both of these services to live a normal life.
