I'm glad that social media platforms remove people violating community guidelines, whatever they are. I don't want people here on HN who do nothing but post flamebait, and I don't want people on Twitter who do nothing but post hate speech. I don't want platforms to be required to host any and all people.
But it's critical that politicians can reach us by whatever means we're using. They are a special class of people, because they're the people we're choosing to represent us. If a political candidate can't reach an audience because they don't agree politically with the platform providers, that's a big fucking problem for democracy.
