Good alternatives are always needed, though! I love Sync, but then I am also not sure it would be as good as it is today if it wasn't compelled to stay competitive with RIF, Baconreader, Apollo (to a lesser extent) and the dozen other Reddit apps that used to be out there (F in the chat).
I wish the Apollo dev would've ported his app and migrated his user base. IMHO, Syncs popularity shows that the developer was able to migrate a lot of their old user base to Lemmy.
