Does anybody know why it so happened that there's literally
nobody else out there besides jepp in aeronautical charting

them, and all this info is publicly available. Yet, the only
commercial enterprise harvesting there is jepp. Between NACO and
them there's a substantial gap in terms of pricing and packaging
of services. Why is it empty?

First guess would be that there isn't enough money to be made to make it
worthwhile.
