Can you elaborate on “limited”? Surely that is what we want. One of the problems with the Play store is certainly not that it does not have a wide enough selection, but rather that it is full of harmful, hostile, dangerous, exploitive software. Any solution to that problem is necessarily going to limit (or one might prefer to say curate) its contents. That is exactly why I use F-Droid. It is limited to software that is not trying to hurt me.
