Fedi's has a distinct echo-chambering problem, as a direct result of the flexibility and distributed nature of the platform.
In part due to what's mentioned in the previous two posts, but it fundamentally comes to how fedi pre-emptively dictate not just how, but who people are allowed to communicate with through opinionated lists at an administrative level.
This is effectively [shadow-banning](https://en.wikipedia.org/wiki/Shadow_banning ) groups of people (servers), due to rumours and/or disagreements between individuals or a subset of the group's members. Cutting off communication between the groups entirely while enforcing a binary "with us/against us" view, where a middle-ground cannot exist.
By definition, these behaviours will continue to fractionalize fedi into [echo chambers](https://en.wikipedia.org/wiki/Echo_chamber_(media) ) that will expand further away from each other while disincentivising finding a common ground.
By setting personal ideals as required rules of cooperation between divergent servers, we self-sabotage the platform as a whole
