I wrote a pile before I realised it was largely irrelevant, especially since the largest platforms are also the easiest to handle. The easiest one to handle first would be the topic-agnostic platforms. Those also tend to be the biggest ones. Facebook and Reddit as the bigger examples. For these, the answer is simple: Let users create whatever they want and apply rules however they want, but allow the rise of new communities. Perhaps a community forking system can serve as a countermeasure to network effects. However, the key thing here for these platforms is that the platforms themselves are barred from impeding speech. The individual subcommunities and their respective leaders are not. As such, there's a clear line between the platform and it's community and subsequently the roles and responsibilities of each. After all, the key difference here is that between publisher and platform.
