>They aren't self-anointed. We anointed them by using their platform

Nahhh, it's way more nuanced than that. They started as user friendly simple services with little to no purposeful mass censorship. Then the user base grew into the billions effectively creating captive audience due to the network effect. Then they became increasingly user hostile (i.e. switching from chronological timeline to a psychologically manipulative news feed) and got into the business of political mass censorship and electioneering; like a bait and switch.
