Ok so for my own erudition --
I understand Hubzilla and Osada are functionally the same product, except Hubzilla uses Zot (Zot6 in dev branch now?) and Osada uses ActivityPub as their primary federation protocols, respectively. What I'm curious about is where Friendica sits -- it seems to also use Zot/Zot6 for federation but if that's the case then why are there both Hubzilla and Friendica?
Anyone have any insight? Looking for a history lesson here. :D
