@joepie91 A decentralised, ahem, open, ahem, protocol controlled by a for-profit entity or consortium might be enough to side-step a lot of the mandated interoperability legislation that’s coming. Depending on implementation complexity it might be feasible to gatekeep participation in the network. I wouldn’t be surprised if we start seeing weird tie-ins for content monetisation etc. too once they’ve got an initial version going.

Maybe my brain is playing too much 3D chess here but who knows.

@joepie91 Fediverse is good example for why you might want to uncouple moderation from the capability for people to associate with each other. If your friend's instance is blocked for reasons unrelated to them and yourself then one of you is forced to make a decision to move. And if the block was related, and there's been a mistake, well then you're on your own.
The moderation features of AP implementations are so barebones that moderators have to operate with the maximum amount of caution for not just their own safety but everybody elses. And that makes for very hard boundaries and an environment where communication between different parties rarely can occur. Either because there isn't the energy or there is no way to determine the risk that you are going to experience abuse by moderating a dispute.
