From the article: Moving to the Fediverse This tension between these communities and their host have, again, fueled more interest in the Fediverse as a decentralized refuge. A social network built on an open protocol can afford some host-agnosticism, and allow communities to persist even if individual hosts fail or start to abuse their power. Unfortunately, discussions of Reddit-like fediverse services Lemmy and Kbin on Reddit were colored by paranoia after the company banned users and subreddits related to these projects (reportedly due to “spam”). While these accounts and subreddits have been reinstated, the potential for censorship around such projects has made a Reddit exodus feel more urgently necessary, as we saw last fall when Twitter cracked down on discussions of its Fediverse-alternative, Mastodon.
Interesting questions… well they would have to pick a protocol(s) and implement them. They would have to comply with the mechanics and the licenses.
For example here is the ActivityPub rec. Given how non interested reddit seems to be in developing… anything… that is not directly $$$-oriented it’s hard to imagine them doing all this. But if they for some reason decided to make a take over of the fediverse and put their back into it? It would be a totally different reddit and I can’t imagine it.
