Just one thing to note about section 230. Amazon is protected from civil liability for content on Parler, but it is not protected from criminal liability. In practice the feds don’t go after isos from hosting criminal content (frauds for instance) with the exception of child pornography, but there is a lot of very illegal stuff on parler right now (calls to kill the Vice President, conspiracy to sedition, etc). It’s not surprising parler is being banned
