Except that the Daily Stormer is still online. As long as net neutrality exists (in practice if not in law) there is no "infrastructure-level censorship" to speak of beyond a slight lack of convenience. What is the worst-case outcome of DNS registrars refusing to do business with nazis? People who want to visit nazi websites would have to type in numerical IP addresses.

The only "infrastructure-level censorship" we should worry about is the Internet itself. As long as you can set up your own servers and host your own services, your free speech rights are not really in jeopardy. Free speech does not mean you have the right to buy the megaphone of your choosing; it does mean that you can voice your opinion using a megaphone, even if you had to assemble the megaphone yourself.
