I see several issues...
Amazon is a private company so it can do what it likes, for one.
Are they and these other tech giants preventing people from setting up new host sites? Everything is so intertwined these days.
Should anyone be forced to host entities calling for/promoting insurgency and political overthrow in the name of free speech? Parler, apparently removed Lin Wood's posts calling for Pence to be executed. Good? Bad? When stuff like that gains enough of a following to push people to act, like we saw this past week, and we have a President openly supporting it...what then?
1. Parler said they will setup their own site, so we'll see if they can keep it running
2. Who is calling for an insurgency? The DC chant was "stop the steal", it was a protest about voter fraud.
3. If it was an insurgency they would have had guns instead of flags.
4. I agree that calls to violence need to be filtered out.
5. Trump supported what? He called for "a peaceful transition", but wants voter fraud reduced in future elections.
