Not going to happen, despite these costs and strictures, media companies still stand to make money so they will play ball. And the US committee is just following the Olympic committee, who have demanded (and gotten) similar injuctions against nasty free-loading IP pirates in previous editions of the Games. SA gave them special IP police. And some details were published from the Bid Book instructions given to the Dutch commission when they were preparing their bid. It had plenty of provisions to very strictly enforce what went on in the stadiums (including tweets), and they even demanded that all neon signs for beers other than the sponsoring brands to be removed from bars in a 3 km radius around all olympic locations. Oh and they wanted highway lanes closed off at set times so the brass could quickly shuttle between locations in their limos.
It's the countries who should tell them to screw it. Sadly they will not do so either, the Games offer prestige and an enormous opportunity for politicians to shine (and have their pals make a bit of cash too). And the Olympic Committee know this, as well as the fact that if you can put something good on the table (or under it), any politician is willing to bargain, no matter how outlandish your demands.
