Nothing about ActivityPub is specifically "twitter-like". In fact the protocol itself, if anything, is way more facebook-like than twitter-like (and largely derives from the facebook-like pump.io). It just so happens that the largest implementors are Twitter-like. But that's not reflective of any protocol restriction. https://news.ycombinator.com/item?id=16836027
We also designed the thing *so Diaspora could adopt it*, even though that didn't happen.
That's not a hit on Diaspora, which moved forward with their protocol because a lot of work had gone into it, but there's a lot of FUD that's gone around that "well Diaspora couldn't use ActivityPub because it's not Facebook-like". I have yet to see anything in Diaspora or anything else facebook-like that couldn't be handled by the AP protocol.
@cwebber I guess you already read this blog post by one of their maintainers? https://schub.io/blog/2018/02/01/activitypub-one-protocol-to-rule-them-all.html
@schmittlauch @cwebber If I remember correctly that post made me 
from how wrong and also condescending it was
