Be stupid brehettes.
Freedom of speech just means you can speak without getting beat, imprisoned, killed or targeted some other way. It does not mean that private companies have to give you a platform. Whether you're talking about Facebook, Twitter, Book Publishers, TV Networks, etc. They have the right to refuse service to anyone, especially if said person espouses views that conflict with their viewers, their brand or their investors. People need to take a trip to China so they can see how totalitarian governments get down and stop making these asinine arguments. Jack Ma still hasn't been seen publicly yet. They got billionaires locked up for twenty years over in China for talking bad about Xi Jinping. That's free speech being denied to someone. Not being kicked off Twitter for inciting violence and getting cops killed.
