True, but this is a new age. Traditional media and even tradition spectating have changed dramatically and continues to change dramatically. Soaring has an opportunity to get ahead of that rather than constantly trying to catch up. Spectators are now world wide via a smartphone either live or via a recording of live video (or edited summary) watched at the spectators leisure.
I think soaring Olympic spectators could be at the airport over a big screen just like sailing often is (see first link below). Imagine watching small boats race 1 mile away. Not very exciting in and of itself. That's not really what those spectators are there. The spectators are there to support the sport and be a part of it. They are watching the movie screen to see the on the water camera footage. At least with soaring they can see the actual finish up close from this position.
Here is the most recent Olympics sailing event as an example...
This one shows a good view of 5-10k spectators watching the sailing event from the English shore in the very beginning of this video:
