I recommend https://www.youtube.com/watch?v=pW-SOdj4Kkk on this topic.

they were looking for unmoderated corners, not for places not powered by money and profit. Which I find orthogonal to the comment from OP. That there’s some overlap on the end result doesn’t mean OP was biased at all.

All of this could be there with the matrix.org protocol. The matrix protocol saves the comments and content in a directed graph, and that graph is copied to every instance, once one views it. It may not scale though. But it has benefits, such as encryption (making communities private or gated when under attack)
