Technically it supports federation, similar to Lemmy. But there’s still only one instance. I don’t know if it’s due to the immaturity of software or something else. If someone want’s to try the code is there.
I think the presence of ActivityPub (basis of Lemmy) already attracted most people willing to bother with hosting an instance so the potential adopters are not very incentivized to experiment with another thing.
The Antichrist story in the Bible was written abstractly enough that it can apply to many people. It’s a warning about a specific personality profile that is universal in history - a sweet-talking, extremely popular, but ultimately harmful leader.
Of course it’s all wrapped up in early Christian language and many metaphors, making it hard to parse for modern audiences. Depends of course on how literally you take the Bible - I’m on the side of those stories being hypothetical lessons rather than exact prophecy.
