Soapbox imo has to be one of the nicest front-ends for pleroma/mastodon style activitypub platforms, but it was intimated there were some reputational issues with it. Not up to speed I did a small amount of digging which led to plermoadrama.
The creator/maintainer holds certain viewpoints that are at odds with others in the community, to the point he recently declared Pleroma to be dead rebranding his pleroma-be approach as rebased.
In addition - one of the contributing developers created a fork called Akkoma based off a schism in the community, where they declared their (lack of) faith that pleroma dev will ever recover.
Pleroma are currently working towards a 2.5 update.
Very well done post, cool cites
