Yes, but afaik the only threadiverse software that is a fork of a previous project is Mbin (specifically forked from the defunct Kbin). Lemmy, Friendica and Piefed are, to my knowledge, all forum softwares made from scratch, therefore independent from one another, all implementing ActivityPub in a way that make them work as thread posts and thus federating with each other.
isn’t lemmy open-source and forkable? like they released it for people to fuck with
