Bluesky blew itself up cos they failed to be sufficiently decentralised and became an echo chamber. Activpub systems are less echo chambery but still have a very strong left lean that is significantly effecting out ability to grow especially among the centre who represents the majority. We need more right wing opinions and allow said right wing opinions if we want the majority of people to adopt it.
The fundamental failure of the fediverse that is limiting us is that accounts are not transportable. We need some decentralised ledger of accounts that can be cryptographically verified with a zero trust system. U just set up a oidc server to do that auth and that plugs into every single fediverse application everywhere.
