This is my main worry. I’m not worried about Parler getting taken down, they have no intrinsic right to have access to these stores hosted by private entities. They can self host, or find someone willing to host them, or implement moderation so they don’t have people calling for the death of senators on their service.

But I am worried this will light a fuse towards further radicalization.

Radicalization because they're too lazy or too dumb or whatever to create their own platform. I'd be mad too if I couldn't harass folks and spread my hate easily.

^ the irony

Twitter now allows me to follow a diverse group of people who promote a different set of norms, value and ideas. It shows me how other people think and I'm exposed to that. That cross pollination isn't going to happen when every tribe has it's own platforms.

What I see happening is Pillarisation [1].
