I have gotten one dismissive reply, so let me add something: Blind fanaticism isn't just unnecessary, it actively prevents positive change from happening because it refuses acknowledgement of problems that always do exist. Nothing is perfect.
I have criticized the fediverse a lot over the years. Especially the instance = community boundary is a huge problem because they serve as both a social space and a gateway to the network all in one package. However, community matters and provider matters are very different. If an instance defederates from another, people don't just lose access to that community - they lose access to communicating with people on an instance entirely until they create a new account elsewhere.
Imagine if a Discord server admin banned you and Discord also blocked your communication with the server members even in other servers or 1-on-1. That's fedi.
This means your choice of an instance is extremely important and happens at a time when you don't even know anything about the fediverse at all.
This is why I think what absolutely needs to happen here is to give instances less importance by implementing communities on a higher layer, independent of those boundaries. Is this happening? I doesn't look like that to me. Hell, we don't even improve on the microblogging formula in a meaningful way. I think the ecosystem at large has become complacent with the existing structure and has no interest in making fundamental changes.
ATProto seems closer to the ideal I have in mind, so obviously I've taken an interest in it.
