Amazon and these large players will absolutely be asked by governments around the world to intervene in similar situations. Sometimes the fraud will be false, but sometimes it will be real - that's the world. Is it now Amazon's job to be the world election supervisor and arbiter of truth and shut down dissenting speech?
And can we trust these companies to act as neutral arbiters of the truth? (As an aside, the answer is absolutely not. See: Google Maps and Crimea / Ukraine / Russia)
You said individuals make their own assessment based on the “evidence” - the problem here is that these companies serve up the “evidence”, so if these companies decide to only show you the “correct” evidence then that’s where they begin to define “truth”.
For an example, see Google Maps and Crimea in Ukraine vs Russia.
To be clear, I fully side with the U.S. courts here. What I'm saying though is governments and officials lie, you can't always just trust the official story.
If parler were used for inciting civil disorder in Venezuela over the election result and the government comes to AWS and says shut them down, what do they do?
Now suddenly they're the arbitrators of what is true in the world.
I don't want to get too hypothetical here, because I think this time it was pretty black and white.
