Fediverse

That could be true. People do seem to tend to tolerate slow declines in platform quality surprisingly long before jumping to available alternatives. I think that's at least in part due to that 'critical mass' effect described elsewhere in this conversation that makes people prefer to stay where they believe everyone else is.

If federation does end up being the only solution that pans out, I hope to see additional approaches beyond ActivityPub. As capable as it is, its design seems to confound any implementations of private communications or revocation of access at many levels where it would be very useful and empowering to admins, moderators, and regular users alike.

I would love to see a federation model where each user has an encrypted profile and content in their own archive that they manage and/or have stored somewhere for them, which they can then use to join servers and choose what data from their profile they share with who else on that server, as well as participate in server local and federated public channels, as well as private data exchanges facilitated but not readable by the server or federated network of servers you have a user account signed up.

I'm not sure it could promise revocation for all data on servers of unknown configuration, but could accommodate info that is facilitated by but not readable by any of the participating servers. Posts in public areas would have and require much lower revocation/deletion assurances, but could still have them in a manner at least as robust as ActivityPub.

I've been watching the space as time permits and am interested in a lot of the amazing things people make for free for the 'love of the game'!
