The likely answer to this is that there will always have to be a large corporation at the heart of Bluesky/ATProto, and the network will have to rely on that corporation to do the work of abuse mitigation, particularly in terms of illegal content and spam. This may be a good enough solution for Bluesky’s purposes, but on the economics alone it’s going to be a centralized system that relies on trusting centralized authorities.
If it’s easy to self host, why is there none publicly available?
Because there’s little incentive.
Anyway, wafrn does count, in my opinion.
There’s as little incentive to host a Lemmy instance.
I am having a look at wafrn, do you have an example of a Bluesky account visible from there? I only see local accounts.
