Protocols, Not Platforms: A Technological Approach to Free Speech (2019)
Reading the comments I think most people misunderstood the point (which is probably the author's fault).I don't think he was saying that they're should be zero moderation, or that moderation is wrong at all.I think his point was that there should be open protocols and then services that use those protocols with their own rules.Examples of this IMO are HTTP, the telephone network and email.
If you don't like your internet provider you can move to another one and you know that every single webpage will still be accessible through HTTP. 
The same way you can call any phone number, regardless of whether the person you're calling has the same phone company. 
The same way you can send an email from Gmail to Hotmail or any other email provider. 
The same is not true for Facebook or Whatsapp. Signal cannot message to Whatsapp.The point is somewhat similar to the Adversarial interoperability EFF article.
