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.
No reason it has to be one cooperation. Could be multiple different appviews ran by trusted entities.
And if my grandma had wheels she'd be a bicycle.
If it's disadvantageous to the money in control of it, it won't happen.
It is happening though. There’s workgroups trying to get their own AppView up, the https://freeourfeeds.com/ initiative announced yesterday, and then moving the register to an ICANN-like consortium.
