Sync for Reddit was a popular-ish third-party Reddit app. The dev has been working on building a version of it for Lemmy, and the surrounding community has been pretty excited for it. Recently, Sync for Lemmy was released, and there's been a lot of fanfare, conversation, etc. In my opinion, it's the most polished Lemmy client by far. Some people are annoyed that the premium features cost significantly more than they did in Sync for Reddit. The dev said it's to offset the smaller user base, which seems reasonable to me, but it's spurred a lot of arguments about the paid model.
