Numerical weather prediction is a public good, produced by national agencies and available to anyone. The scarce thing has never been the forecast - it is knowing which of your assets, routes and counterparties sit under it, which is a question about relationships rather than about meteorology.
That resolution is the work. A cyclone track crossing a shipping corridor matters because of the specific equipment on the specific vessels using it; a heat event matters because of the grid it derates and the load underneath. Neither statement can be made from a forecast alone.
