I do not know the nuances of free speech doctrines. I'll take your word. Assume all tech companies de-platform Joe Rogan fearing retribution from other customers He buys a Ubuntu box to host the videos. And now he needs a static IP and a domain name. Are DNS providers considered in association to Joe Rogan's speech if they sell him a domain name? Seems to be true going by the assumption that DNS providers are tech companies. If so, should the DNS providers decide not to sell Joe Rogan a domain name fearing retribution from other customers, and as a consequence Joe Rogan is practically NOT visible on the internet at all to any reasonable person, isn't that not in the spirit of free speech?
