A lot of the value isn’t technical, it’s social. Each instance can set their own rules for acceptable conduct and what sort of content they want or don’t want. That’s one of the most valuable parts of decentralization, an instance like Beehaw can try to be an open and inclusive space and thus have a longer list of rules, while another instance can be more permissive and allow NSFW and more offensive speech. And thus the two can coexist in the same network with the same namespace.
