First, are you not thinking of Liquid instead? That is run and developed by a private company. Lightning does have some big nodes, but in general the interconnection is pretty good, as far as I can see [0]. If you want to route payments, it's not enough to just have channels going to you, but you also need to have outgoing channels to balance the flow, and you are on the hook for the closing fees, so that should help with stability.
