Parler would have never been a business. Because, for some reason, those gatekeepers weren't entirely terrible in keeping really obvious and obnoxious assholes far away from their printing presses.

And let's be clear: nobody gets "literally destroyed", nor even figuratively, for publishing "one wrong thought". Parler had been peddling in low-effort violence-porn for the lowlifes that make up their userbase for what.. two years? That's hundreds of thousands of terrible... "thoughts". And nothing happened, until something happened, which happened to be peoples' deaths and a crisis of democracy.

For comparison: reddit got into hot water at some point, and managed to clean up their act. The porn websites are in a similar process. It's all just actions-have-consequences, really. And the public's ire is actually the more nuanced, soft approach to do it, compared to the blunt tool of criminal law.

Nothing is stopping anyone from starting their own webhost. Free market economy etc.
