Huh? What do you mean by exclusive rights?
Fox is available on OTA in the US and pretty much every weekend you can watch golf on the OTA channels like CBS and NBC. Here in Canada the majors have been on a pay channel (TSN) for the most part for years and it hasn't hurt our participation which is very high. But most Canadians also get the main US channels (ABC, CBS, NBC, Fox) with a basic cable/sat subscription.
