What a fantastic idea. They don't even have to necessarily pivot their apps to actually be Lemmy clients to deliver a massive "fuck you" to Reddit. They collectively have a large install base. Instead of a warning banner saying, "This app will cease functioning on July 1 (or whatever the date is)," they could add, "Check out our new community over on Lemmy [with a link to whichever Lemmy client]." If I were a Reddit app dev, I would 100% be incorporating this threat into my talks with their team about the forthcoming reddit API.
