An approach 3rd party apps can take could be just hiding the “different instances” aspect of the lemmy and just registering users to a certain preselected instance such as lemmy.world or lemmy.ml I don’t know how legal or viable it is but I don’t think it would cause much difference for most of the users. Though I feel like hiding a crucial aspect would be a kind of shame.
