It's an interesting article.
What it clearly shows is what we've all known for a long time, you can't make money out of hosting an F1 race so your buisness model needs to be watertight and cover as many diverse methods for raising cash as possible. There was a time (though I don't think he does anymore) when dear old Bernie insisted that any circuit wanting to host an F1 race could not hold another major motorsport event.
With the general lack of interest in F1 stateside, Team Haas can't join the grid soon enough for CotA.
